Andre Johnson...good for years to come. Especially if you get pts for receptions or big yard games. Its a gamble, but like you said he just simply can't be relied on all year.
I am a little bitter though, I trade him right before the deadline (along with Eddie Royal) for Chris Johnson and Plaxico. This was right before Westbrook blew up the last couple wks and right before Plax shot himself. (I wish he would have hit his little wiener!
