The Rams have announced that backup QB Kellen Clemens will start on Monday Night Football for the Rams as they host the Seattle Seahawks to the Edward Jones Dome.
Clemens' last real action was back in 2011, when he started three games for the Rams. Clemens went 48-for-91 for 546 yards passing, two touchdowns and one pick in those three starts, and that put him, per Football Outsiders, at -6 DYAR and -12.0% DVOA on the season... which isn't very good. Clemens is the definition of a journeyman, and previous to those three starts in 2011, his last meaningful snap came back in 2007 for the Jets. Obviously, facing Seattle's stifling defense isn't an ideal situation.
Nonetheless, Seattle must be ready for a dogfight. It's the NFC West, the Rams are backed up against the wall, still have a good defense (or at least, still have good individual defensive players that I respect), and are playing at home.
