As a pure WR, he is definitely better than all those guys, except, like you said, Hopkins. Could go either way there.
I could've sworn that I read that there were some personality concerns with Woods.
Like you said, he was a scrappy, fiery guy and I wasn't really surprised by his clash with Marrone. And c'mon, he played him with the two's in a preseason game. Talk about a non-factor on the season for a punishment.
