NORMAN, Okla. -- Oklahoma coach Bob Stoops thinks that Heisman Trophy winner Sam Bradford has come back noticeably improved for his junior season.
Bradford broke Oklahoma single-season records with 50 touchdown passes and 4,720 passing yards last season, but he appears to have more confidence and a better deep arm after the first week of Oklahoma's practices.
"He's strong, he's quicker and the ball comes out that much faster," Stoops said. "With another year of experience out on the field, he'll think much quicker, too."
Bradford appears noticeably bigger after adding 10 pounds of muscle since the end of last year.
"Sam is getting better each and every day," senior wide receiver Adron Tennell said. "Throwing the ball, rolling out of the pocket, he's done it all. You can tell he's better than before."
Stoops said there's little separation between his backups who are playing behind Bradford at quarterback.
Redshirt freshman Landry Jones was presumed to have the edge, but redshirt freshman Ben Sherrard, junior John Nimmo and freshman Drew Allen all are in the mix for playing time.
"Those guys are still splitting their reps," Stoops said. "We keep snapping the ball and giving them experience. They are working well together and doing a nice job."
Sophomore defensive back Jamell Fleming has been hobbled by a back injury and sophomore defensive back Desmond Jackson "has an issue with academic misconduct" that he's working through, Stoops said.
Oklahoma's special teams have looked strong in recent practices. Kicker Jimmy Stevens showed improved range at Thursday's open practice with field goals of 50 and 53 yards.
Stevens' length is a big development for the Sooners. His longest kick last season was 42 yards and he shanked five extra points.
Stoops playfully chided about 300 fans who attended the Sooners' open workout Thursday night that they weren't cheering loud enough for Stevens' big kicks.
"They only cheer when there's an offensive play," Stoops said. "When the defense intercepts the ball they are quiet over there or when the kicker gets a nice 53-yard field goal."
One of the early revelations of fall practice has been wide receiver/punter Cameron Kenney, a transfer from Garden City Community College.
Kenney has jumped into the mix at wide receiver and also is challenging for the punting position against Tress Way. It's a weird combination of a speedy wide receiver who also is a strong punter.
"He's pretty good," Stoops said. "He's shows a lot of signs (as a receiver), but he needs to be more consistent, but he's doing a lot of good things.
"He's punted well, too. It's very rare because you don't see a lot of wide receivers who can punt the ball 40 yards like he can."
Oklahoma receivers coach Jay Norvell said that Kenney reminds him of former Oklahoma wide receiver Juaquin Iglesias because of his combination of size and strength.
"It's because of his quickness, his way of getting in and out of plays and the fact he's very strong to the ball," Norvell said. "Cameron can also run well after the catch. He's a hard worker and the guys who work the hardest get better faster."
Despite the loss of key playmakers like Iglesias, Manny Johnson and Quentin Chaney from last season, Norvell thinks his current group has the chance to be better than last year's productive group.
"I think we're more athletic and explosive than we were last year," Norvell said. "Whether that will correlate into productiveness, I'm not sure. But we have athletes and in that respect we probably have more deep threats than we did last year."
