Strengths: Jenkins is a fast player who plays fast. He gets in and out of his cuts quickly. The 49ers drafted Jenkins much higher than many predicted, yielding higher expectations for the rookie. The team needed to add a vertical dimension to the offense after last season.
Weaknesses: Weighing in at just 192 pounds (and 6'0" tall), Jenkins needs to add bulk. This will help in the middle of the field. A one-dimensional threat has limited upside, Jenkins has a low ceiling until his route running improves since quarterback Alex Smith isn't overly adept at the deep game.
2012 Outlook: San Francisco is a team with many receivers in front of Jenkins on the depth chart. The rookie will not get many pass targets in 2012 as long as Randy Moss, Mario Manningham, and Michael Crabtree are ahead of him on the roster. Also hurting his chances of making an immediate impact is Smith. It is doubtful that the weak-armed Smith will be able to find Jenkins often enough to make him viable for fantasy owners. Avoid in redraft leagues.
Dynasty Outlook: If he can improve his route running, Jenkins has a chance to make a big splash in a couple of years as Moss will likely be gone by then. With Crabtree on the roster, Jenkins' upside is likely ultimately limited as San Francisco's WR2, but he can still be a decent a fantasy option eventually.
NFL Comparison: Jenkins' blazing speed and slight build are reminiscent of DeSean Jackson. Both have the speed to make plays, but the lack of physical size limits upside.
