I don't know why he was on the team this year....Lee Smith, Tyler Kroft both should be gone too. Kroft had 6 catches in 11 games. WTF is he on the team? I would start Sweeny over Kroft.
The big question is WHY was DiMarco even on the field during a critical time in the game? The only way I see that is if your other RB's are injured and they weren't.
