The Rams may not be in a position to rest anyone come Weeks 16 and 17. Regardless, QBs usually don't get rested at all before the playoffs due to offense chemistry issues.
RBs that typically get 15-30 carries per game are the players that might get their workload cut back: Priest (in favor of Larry Johnson), Stephen Davis (D Foster), Eddie George (C Brown), A Green (Fischer or Davenport), J Lewis (C Taylor), D McAllister (K Carter), etc.
Chris Brown, who looked great for Tennessee in the 2nd half Sunday, is a good sleeper for Weeks 16/17. As is DeShaun Foster.
