One of the more impressive things during offseason workouts for the San Diego Chargers was watching how efficient quarterback Philip Rivers ran the offense.

Rivers seemed to pick up where he left off last season. Few balls hit the ground during two-minute drills, as Ladarius Green, Keenan Allen, Malcom Floyd, Vincent Brown and Eddie Royal made catches all over the field.

Add to that a diverse group of running backs in Ryan Mathews, Danny Woodhead and Donald Brown playing behind an experienced offensive line, and the Chargers should have one of the best offenses in the NFL for a second straight season.

“I think they did a nice job,” San Diego coach Mike McCoy said. “For a majority of the guys it’s their second year in the system, so that’s going to come with time. The more you’re in a system, the more comfortable you are. And if you have a quarterback like Philip Rivers, good things are going to happen.

The Chargers lost OC Ken Whisenhunt to Tennessee but will enjoy the return of WR Malcom Floyd. Rivers looks like a good value given his current ADP.

Titans WR Justin Hunter let us in on a little secret the other day.

Asked about the difference between the Titans' new offense and the one they ran last year, Hunter said: "We're throwing it downfield a little more."

A couple of thoughts:

Maybe the Titans plan to throw the ball downfield with greater regularity because that's HC Ken Whisenhunt's philosophy.

Or maybe they'll throw downfield more because Hunter, now a second-year pro, gives them another serious playmaking option in the passing game.

Most likely, it's a combination of the two. The offense is evolving. Hunter is developing. It's a good match.

Whisenhunt's preference for three-wide receiver formations (that was the primary alignment in San Diego last season when Whisenhunt was offensive coordinator), Hunter should be on the field with Wright and Nate Washington a majority of the time.

As a rookie, Hunter checked in with the #18 FP/T (1.41), which is encouraging. He only played 36% of the team’s snaps, while Washington played 82%. The good news is that under then-OC Ken Whisenhunt, Keenan Allen, Vincent Brown and Eddie Royal all played at least 67% of the Chargers’ snaps. So with Whiz calling the plays in Tennessee, there may be room for both Washington and Hunter in the lineup.

On the hype surrounding Eagles WR Jordan Matthews...

In the past decade, four rookie wide receivers - Michael Clayton, A.J. Green, Keenan Allen and Marques Colston - have had 1,000-yard seasons. Five - Eddie Royal, Clayton, Allen, Dwayne Bowe and Colston - have had 70+ catches.

And there's this one from Brent Cohen of Eagles Rewind: 49 receivers have been taken in the second round since 2000 and played at least 10 games as rookies. Average receiving yards for that group has been 437.

All of those numbers are meant for context, and players buck trends all the time. But a really good season for Matthews would be replicating what Riley Cooper did last season, not DeSean Jackson.

Matthews will likely see snaps in the slot (at least) this season. Jeremy Maclin is working his way back from an ACL injury and Riley Cooper is solid, but unspectacular. There is opportunity in this offense if Matthews has a great summer, and by most accounts he has.

One of the primary beneficiaries of the Chargers' no-huddle attack will be Ladarius Green, who was limited to a deep threat role as the No. 2 tight end last season.

Bucky Brooks believes Green is ready to outproduce Antonio Gates as long as OC Frank Reich uses more two-tight end sets this season. The Bolts need Green's speed and playmaking ability down the seam to complement Keenan Allen on the outside.

This sounds good, but there's no guarantee that the team will run more two-TE sets. This sounds more like conjecture than a solid prediction at this point. Stay tuned.

When asked who will start opposite Keenan Allen, Chargers beat writer Michael Gehlken replied, "Tough to match Malcom Floyd when healthy. He's been real impressive during OTAs."

From 2010 to 2012, Floyd finished #36, #32 and #36 as the second or third option in San Diego. He returns from a neck injury at the age of 32 (turning 33 in September) and will compete with Vincent Brown to be the team’s WR2 opposite Keenan Allen. Brown flopped in a starting role (scoring just 0.06 FP per snap) last year, so the job is Floyd’s for the taking. If he’s starting and can stays healthy (a rather big “if”), he should be fantasy relevant once again in 2014.

Chargers WR Keenan Allen should benefit from the return of Malcom Floyd. The 6-5, 225-pound receiver has been a surprise addition for the Chargers, returning from a serious neck injury and looking like his old self during offseason work.

From 2010 to 2012, Floyd finished #36, #32 and #36 as the second or third option in San Diego. He returns from a neck injury at the age of 32 (turning 33 in September) and will compete with Vincent Brown to be the team’s WR2 opposite Keenan Allen.

If he’s starting and can stays healthy (a rather big “if”), he should be fantasy relevant once again in 2014.

According to U-T San Diego, Chargers WR Malcom Floyd will play in 2014 following a career-threatening neck injury suffered early last year, per team and league sources.

"The doc said ... I'm at risk just like anybody else," Floyd said Monday. "There's not really a worry. As far as going out there and performing, I'm really excited to make plays again. Hopefully, I can do more this year than I ever have. ... I'm feeling good. I think I feel like my old self."

It's outstanding news for a Chargers offense that could use another deep threat. Keenan Allen is coming off a monster rookie year, but the Chargers lacked depth with only Vincent Brown and Eddie Royal on the chart. Floyd will be 33 years old this season, but he topped 800 yards in back-to-back seasons in 2011 and 2012 before getting injured early last season.

Floyd had three straight top 36 finishes from 2010 to 2012 before the injury. He's a capable real-world WR2 if healthy, but it's not clear where he'll fit on the depth chart with Vincent Brown and Eddie Royal.

ESPN's Matt Williamson talked about Chargers WR Keenan Allen:

"As much as I like Allen, to ask him to improve dramatically in one season may be asking too much. He's a really good receiver, but he does not have the athletic ability of an A.J. Green or a Julio Jones. He could be close to his ceiling already.

Williamson added that Allen is an advanced route runner and has good hands, just lacks speed. He pointed out that teams will have another year to study him, too. Still, Allen was really the only WR threat on the Bolts last year, but put up nice numbers despite getting the full attention of defenses. He should fall in the WR2 or 3 zone with potential to exceed that in certain matchups.

Danario Alexander devoted months to knee rehab, working to return from an August injury as soon as possible.

It won't happen as soon as first hoped.

The Chargers wide receiver recently underwent additional surgery to repair the right knee injury that ended his 2013 season, sources said. The revision ACL surgery, performed in January as a follow-up to the primary reconstruction done in August, delays the original timetable for the impending free agent's return to football activities.

It doesn't look likely that Alexander will be healthy to start the 2014 season. It's a shame too -- he and Keenan Allen would have made a dangerous duo for the Chargers. He was outstanding down the stretch in 2012.

The Tennessee Titans have hired San Diego Chargers offensive coordinator Ken Whisenhunt as their new head coach.

Whisenhunt replaces Mike Munchak, who parted with the team after three seasons and a 22-26 record.

Whisenhunt led a revitalized Chargers offense led by QB Philip Rivers, RB Ryan Mathews and WR Keenan Allen. His first order of business will decide who is the future at QB. Jake Locker has been inconsistent, but the Titans hold the #11 pick. Ryan Fitzpatrick could hold down the fort for a year if necessary.
