It's a fair question, but one with an easy answer. Kellen Clemens started the majority of games for the team at quarterback in 2013. Shaun Hill and Austin Davis split starts at quarterback in 2014. Former offensive coordinator Brian Schottenheimer's gameplans and the team's rotating cast of midlevel starting wideouts also didn't help.
It's far too early to make any judgements about these Rams. But this Sunday's game in Arizona is a big one for them, and this is a big season for Snead and coach Jeff Fisher. Mathieu might not be the only one wondering why the team doesn't win more games if they can't get to the playoffs this season.
