If I remember correctly, Urbik was a third round pick of the Steelers.
At any rate, I'm not ready to names names, so here I go, in no particular order yet:
LT- so we can move Glenn to RT, if Hairston can't return.
G- serious upgrades needed on both sides
TE- Chandler hasn't shown me enough to warrant another contract
WR- 6-4 or 6-5 would be nice, and the only two we have are on the practice squad
RB- need some depth and Fred has one year (?) left on his contract
OLB- Moats and Bradham aren't receiving a lot of snaps for a reason
DL- Branch is a FA, and who knows if Carrington can return from his injury?
We have more needs than this, so I hope we can work some draft-day trades.
