Who's at fault for Austin's slow start?

When the St. Louis Rams dropped the No. 8 overall pick on West Virginia star wide receiver Tavon Austin, it seemed that he was in position to make a mark as a rookie. He started off pretty hot in terms of activity, catching six passes in each of his first three games, while tacking on a pair of scores in Week 2. Since Week 3, though, Austin has caught a total of just six passes for 43 yards and no scores. He hit rock bottom last week when he played just four snaps and was targeted only once.
