Let's just get the smart-ass response of "he gets injured" out of the way first.
Disclaimer: I'm a sucker for the blazing fast guys. I held out hope for Roscoe Parrish and TJ Graham longer than most so take this all with a grain of salt.
Having said that. I love watching this guy play and I think he needs to be used more. The separation he gets is not something I've ever seen from a Bills player. Yes he gets hurt a lot, but he's not a wimpy player. The guy goes into the middle and will take a hit to make a catch.
For those who have seen their share of Niners games, what role do you see him playing in Roman's offense? I can't recall if they had a guy like him before. Brandon Lloyd is fast, but not really the same kind of player. From everything Rex and Roman have said, it seems like they prefer size and power over the small, fast guys.
Watkins and Goodwin on the ends with Woods in the slot would scare defenses (if we had a QB, that is).
