Cone was very good on special teams at Atl. That might be the reason he's still here ... for now.
Cone is here in case Williams blows out his knee and some team trades us a 3rd for Rishard Matthews. It wouldn't surprise me though if Cone wins a 6th WR job based on ST ability. He's a capable receiver and with 5 pretty good receivers ahead of him, we won't need a world beater in the receiving area.
We need the ST guys to come from somewhere.
