Ill just leave THIS here
If you want him to be a returner only? Ok, he's better than what you have. (Not saying much)
This guy cant run routes, cant find the ball in the air, cant/wont take a hit, will run out of bounds instead of fight for a first down, and wont change your WR corps much.
Again, if cheap, hes a good ST signing. Nothing else. You still need help opposite Smitty.
Worst case scenario is he is Louis Murphy with the added bonus of being a legit return man
