When was the last time a DT recorded 10 sacks in a season, let alone his rookie year?
The answer is Warren Sapp in 06 with the Raiders and I cannot recall if a rookie ever did so recently.
Suh can single handily disrupt a game on his own. Without Suh, I'm not sure the Lions go on their four-game winning streak last season and I know they aren't anywhere near a potential wildcard team they could be.
Raji is a very solid NT. In fact, he is the best NT in the NFC right now, but he is a vastly different player than Suh. Suh plays the three technique in a 4-3 defense, which yes, does allow him to create havoc. However, 10 sacks from that position is amazing. I cannot stress that enough. The rush he provides inside is comparable to players in the Hall of Fame. Right now, he pushes the pocket and creates more havoc in the backfield than any defensive lineman in football creates.
I also would note majority of Raji’s snaps came from a 2-4-5 alignment anyways. He moved out of the nose spot, which is demonized to some extent and into a a more favorable role.
A better comparison for Raji would Ngata, who moves around in similar ways. With that said, Ngata is probably the most game planned for defensive lineman in the NFL. He actually might be the most game planned for defensive player right now, which is why he is No. 3 on my list. Teams will block him with up to as many as three guys to stop him from penetrating the backfield. That frees up those Raven LBs to make the plays they do. Ngata makes guys around him better, as does Suh, which makes them special players. Raji has the ability to make a similar impact someday, but for all his success last season, he has not achieved that quite yet.
