Honestly, I'd say yes (for vet minimum only). We need a jump ball receiver since Dak has had to throw 2 attempted hail Mary's in 9 games so far. With all 3 of our WR's having been hurt at some point in the season, we have to be careful. He could provide to be a useful backup.
I don't think he'd come back with Garrett as coach. Plus he doesn't like Sean Lee for some reason, so there's that...
Also, we never activate half of the other WR's we have anyway (Cedrick and Devin when we've taken a beating WR wise), so would he really make that much of a difference?
