Matt Barrows of the Sacramento Bee believes 49ers WR A.J. Jenkins is likely to be given the best opportunity to succeed this summer. Jenkins is a former first-round pick, and HC Jim Harbaugh had high praise for him in June.
Jenkins spent the offseason working on his biggest weakness in 2012 -- his strength. It was hard to tell whether he made strides during the non-contact practices in the spring, but Jenkins is noticeably more confidant than he was a year ago when he seemed to end up on the ground on every third play.
Training camp, and especially the preseason, will be the true test for Jenkins, who must prove he can operate in spaces far tighter and more violent than those he experienced at Illinois. If he succeeds, his quickness and fluidity would be a nice complement to Boldin's aggressive style. It's also possible that Jenkins will operate out of the slot where he would have more space with which to work.
