The Seattle Seahawks could have one of the best 1-2 combinations at running back in the NFL next season. That sounds a little insane because last year the Seahawks had perhaps the worst 1-2 duo in modern league history, but also is it that insane? Because when it gets that bad, the coaches and personnel folks know how much it has to shift in the other direction. Seattle gets a little lucky by having the return of Chris Carson mean that they didn’t have to go out and get half of that duo — he was already on the roster and he was really, really good in his short stint last season — but then they also used a first round pick on Rashaad Penny.
