While Keenan Allen likely will garner the majority of attention from Arizona's secondary on Sunday, receiver Malcom Floyd will be a likely target on backside routes for Philip Rivers. In San Diego's last four regular-season openers, Floyd has averaged seven targets with an explosive play of at least 16 yards in all four contests. Allen is San Diego's No. 1 receiver, but Floyd has been Rivers' most consistent target during training camp and in preseason play.

We've been recommending Floyd as a late-round option all summer. From 2010 to 2012, Floyd finished #36, #32 and #36 as the second or third option in San Diego.

I wrote several weeks ago that expectations might be too high for wide receiver Justin Hunter entering his second season, considering he only caught 18 passes as a rookie.

But I'm now more inclined to jump on the hype wagon. Hunter has progressed faster than I imagined. He's bigger, more confident and is doing a better job of using his freakish athletic skills to full effect.

While it's true the regular season is a different animal, Hunter appears ready to become a consistent big-play threat.

As a rookie, Hunter checked in with the #18 FP/T (1.41), which is encouraging, especially if he’s able to beat out Nate Washington and get on the field as more than a just a passing-down specialist. 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 players in the lineup if Hunter hasn't already won the job outright.

Throughout training camp and in the preseason, Titans wide receiver Justin Hunter has made the fade pattern look all too easy.

When the Titans get anywhere near the goal line, quarterback Jake Locker simply lofts a soft spiral toward the corner of the end zone. That's when the 6-foot-4, 203-pound Hunter turns into a jack-in-the-box, leaping over defenders to haul in a touchdown pass – just as he did in last Friday's loss to the New Orleans Saints.

It's been all but unstoppable so far.

Hunter's prowess in the redzone bodes well for QB Jake Locker.

Titans WR Justin Hunter continued his run of strong training-camp catches. In seven-on-seven play, he hauled in a Locker pass at the left sideline despite strong coverage from Coty Sensabaugh. A few plays later, Hunter blew past rookie defensive back Marqueston Huff and caught a long pass from Charlie Whitehurst. Hunter also made two leaping receptions during team drills – once in the red zone and once down the left sideline, going up and over cornerback Ri'Shard Anderson.

Ricky Henne of Chargers.com was asked who was impressing him the most at Chargers training camp: " I couldn’t be happier to write that the guy impressing me the most is Malcom Floyd. We all know the scary injury he suffered early last year, so no one really knew what to expect from M-80. What we’ve seen is a player who hasn’t lost a step and is routinely making his patented acrobatic catches and big plays. I asked Offensive Coordinator Frank Reich about Floyd last week, and he said the wideout looks like a 25-year old out there."

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 likely start as the team’s WR2 opposite Keenan Allen. If he’s starting and can stay healthy (a rather big “if”), he should be fantasy-relevant once again in 2014.
