Keenan Allen has focused on improving his speed this offseason. One of the main reasons Allen fell to the third round of last year's draft was a dog-legged 4.71 forty at his Pro Day. But he was coming off a PCL tear and has now been able to put some effort into gaining long speed. Allen, who posted one of the best rookie years by a wideout in NFL history, will need that extra juice as he adjusts to being the focal point of defenses. We're confident he'll be able to make the adjustment while getting peppered with targets as Philip Rivers' go-to guy.
