Could be leagues with smaller rosters. Not everyone is in 12- and 14-team leagues with 20 roster spots. My home league is 10 teams and has 16 man rosters, up from the 14 man roster limit we had for over 10 years.
12 team 16 man rosters NO ONE mentioned here is available. Slim pickings every week. Been runnin two D/ST's all year but I think I'm going to drop one and grab Caddy. Gruden said its been like Christmas waiting for him to come back. "Christmas is Wednesday, I hope" he said. Sounds pretty optimistic to me, but since I have the space I'm going to get him first.
I'm ridiculously thin at RB, largely thanks to SJax. Holding Mewelde until I see Parker practive through this weekend. And waiting for news on Addai and whether he's practicing, so might add Rhodes to this list, likely fairly high if so.
