Carson, a seventh-round pick out of Oklahoma State last year, won the starting job in the Seahawks' backfield in training camp and put together a solid four-week run before breaking his leg and ending his season. It's easy to see what the coaching staff liked about the rookie, as he runs with tackle-breaking power behind a 5-11, 218-pound frame and seems to welcome contact without hesitation. The downside is that he doesn't make many defenders miss, and an injury history that dates back to his junior year in college suggests he might not be able to withstand the pounding his running style attracts. Carson also doesn't offer much in passing situations, limiting his role primarily to early downs and short-yardage spots. The selection of Rashaad Penny in the first round leaves Carson in a tricky spot, though the second-year pro did open training camp with the starting offense. With Penny now uncertain for Week 1 while recovering from a broken finger, Carson is on track to open the season as Seattle's starting running back. Of course, the battle for carries may just be getting started. Read Past Outlooks
