The Seattle Seahawks are looking to improve on a pair of 7-9 seasons under head coach Pete Carroll. Their roster has shown significant improvement since he took over player operations, making it difficult for newcomers to find roster spots in 2012.
Some players will need to make a change this season if they are going to make the final 53 and contribute on the field.
The NFL isn't usually the best location to learn a new position, but there are advantages. They have the best coaches in the game and the practice squad gives players more than one season to learn before being forced into game action.
Seattle is gambling that their coaching staff will be able to transform Bruce Irvin into an every-down defensive end. There are five other players that may also be looking at a transition this season.
