I think some of the criticism is simple sour grapes. I mean how many times have I read on these boards all kinds of praise for a guy that's average - until he is let go, at which point eh, that dude was just a chump anyway. It's typical fan mentality. When he's yours, he is great. When he is someone else's, he's just a guy.
Not saying he's a pro-bowler, but he would fill a clear need, and also be a real help on ST and lord knows we need it.
Sign him Rick.
