http://sports.espn.go.com/nfl/columns/story?columnist=pasquarelli_len&id=2614021 Surprise • QB David Carr (Houston): The top pick in the 2002 draft, Carr spent the first four seasons of his career as a human piñata, sacked an average of once every 8.8 drop-backs. He was sacked 76 times as a rookie and 68 times last season. Carr is still getting sacked too often (15 times in four contests). But when he's been able to stay perpendicular, the former Fresno State star has been terrific, leading the NFL with an efficiency rating of 108.9, and throwing seven touchdown passes versus just two interceptions. If first-year head coach Gary Kubiak can figure a way to keep him consistently upright, Carr might yet develop into the Pro Bowl-caliber quarterback scouts predicted he would be.
