I don't know how it happened, but the St. Louis Rams have managed to leave the 2012 preseason knowing no more or less about Sam Bradford's future than they did going in. His dominant game against the Baltimore Ravens Thursday--11-for-16 with three touchdowns and 175 yards--left him with two great, encouraging performances and two horrific, let's-go-back-in-time-and-draft-Robert-Griffin performances.
One way of organizing these, if you're looking for a little more to hold onto going into the regular season: When Sam Bradford is protected by his offensive line, he looks like Sam Bradford was supposed to look. When Sam Bradford is not protected by his offensive line, you go back in time and draft Robert Griffin.
There's a lot going on, and that's a gross oversimplification. But this is the preseason; it's hard to take anything from it besides gross oversimplifications. If Sam Bradford failed to rebuild fans' confidence in him after his 2011 season took the shine off his superficially better 2010, he also maintained whatever there was left. Which leaves us, heading into the 2012 season, exactly where we were a month ago.
