The Lions were not able to retain defensive tackle Ndamukong Suh, and without taking anything away from the impact he'll likely have for the Miami Dolphins, that's probably a good thing. Suh is a game-changer, but one who would have crippled the Lions financially. Nick Fairley, C.J. Mosley and Andre Fluellen also departed, and all four of those players helped comprise the NFL's best run defense. Without them, the unit is going to look radically different.
Gabe Wright, Caraun Reid and Tyrunn Walker should form the foundation of a solid defensive front. On offense, rookie Ameer Abdullah could be the spark plug the Lions are looking for in their rushing game. The pieces are there to continue competing with the Green Bay Packers in the NFC North, but they may have more question marks this offseason than they did last year.
Ezekiel Ansah, DE
It's hard to believe that Ansah didn't even play football until he was in college. Now, he's one of the brightest young pass rushers in the league.
Tyrunn Walker, DT
You may not know the name, but the NFL does. Walker battled his way on to the 53 man roster with the Saints as an undrafted free agent. When the Saints decided not to tender Walker in restricted free agency, several teams took notice. Walker turned down a multi-year offer from the Patriots to sign a one-year deal with the Lions because of the aggressiveness of the unit.
