I like the idea but I see Jenkins as a pro bowl player/star in the making, not some older player that is just used everywhere, because you don't know where to play him.
Jenkins is versatile. He is good enough to get matched up on TE's and even WR's in some cases, and can play deep centerfield and in the box. He still will get beat from time to time by freaks like Vernon Davis but he is better in man coverage than Harper. I'd like to see him get involved more than just playing mop up duty on the backend.
