Stock Up: Josh Robinson, Minnesota Vikings
Robinson impressed Leslie Frazier with his speed and burst, according to the Star Tribune (via the Aberdeen News), saying, "Josh (Robinson) caught a punt, and he just took off like a guy shot out of a rocket."
Robinson needs to make an impact on defense, but if he can contribute on special teams he'll help this team.
Stock Down: Joe Looney, San Francisco 49ers
According to Cam Inman of the Bay Area News Group, Looney missed time due to a foot injury. Looney's draft stock dropped because of concerns about his durability, and starting off not able to work out doesn't bode well for his rookie season.
Stock Up: James-Michael Johnson, Cleveland Browns
According to Nate Ulrich of the Akron Beacon Journal, Johnson appears to be getting every opportunity to earn some meaningful snaps. He's being rotated between both inside and outside linebacker.
Johnson is a player that I had rated as a second-round prospect. He can easily make an early impact in the NFL.
Stock Down: Luke Kuechly, Carolina Panthers
Kuechly will be starting his NFL career learning a new position. The Panthers plan on starting Kuechly at weakside linebacker, according to Joe Person of the Charlotte Observer, which is a position he isn't really familiar with.
Kuechly will make an early impact but might have been more successful at a familiar position.
Stock Up: Terrance Ganaway, New York Jets
According to Mike Vorkunov of The Star-Ledger, Rex Ryan loves Ganaway because of "the running back's smarts, versatility to play fullback and tailback, as well as an ability to catch the ball out of the backfield."
This is a team that might be willing to take a risk on another running back, as Shonn Green and Joe McKnight haven't locked themselves in as long-term options.
Stock Down: Brandon Weeden, Cleveland Browns
Weeden spent most of his college career taking snaps out of the shotgun, and it seems that he's having some issues taking snaps from center, according to Nate Ulrich of the Akron Beacon Journal.
There are many predicting Weeden will make an easy transition into the NFL, but his age doesn't make him an NFL-ready quarterback.
Weeden needs time to learn the terminology, drop steps and reads.
Stock Up: Devon Wylie, Kansas City Chiefs
Romeo Crennel said, "He showed some pretty good quickness and things as far as catching the ball goes," according to KCChiefs.com.
Wylie will earn himself a role in the Chiefs offense. He's a more refined receiver than players like Dexter McCluster, who the team forced into that role.
Stock Down: Ryan Broyles, Detroit Lions
Broyles had hoped to be ready by the opening day of training camp. However, it seems that that's a real long shot.
His coaches are hopeful that Broyles can make an impact at some point this season. Still, it will take time for him to recover from his injury.
The more time Broyles misses, the less chance he has to win the No. 3 wide receiver role.
