Since last summer, Matthews has been shopped around the league, has requested a trade and is now threatening to displace Kenny Stills in three-wide receiver sets.
After opening training camp on the roster bubble, Matthews started ahead of Stills in the third preseason game commonly referred to as the "dress rehearsal" for the regular season.
"This is the most consistent I've ever seen Rishard," offensive coordinator Bill Lazor said last week. "He's made plays in virtually every practice -- down the field, physical plays, fast plays. I'm really proud of him and rooting for him."
Although Matthews is a former late-round pick who has been in and out of coach Joe Philbin's doghouse, he has shown flashes of potential in the past. His career highlight came in Week 10 of the 2013 season, when he hauled in 11 catches for 120 yards and a pair of touchdowns against the Buccaneers. The disappoint is that Stills hasn't been able to secure the job after coming over in a trade from the Saints.
