his head may not be screwed on right
he called out vick (saying his stats sucked cause the qb couldn't get him the ball, which may be true, but still. and i don't know if he said anything about the situation in dallas (not enough opportunities? bad qb play?), but he didn't get cut for being too good.
still, he's fast (16ypc avg), he can do returns, and he's had some good games not that long ago. at vet min he couldn't be bad pickup... worst case you just dump him again.
