One more thing regarding Suh. I've seen some (not many on here)question his effort and compare him to Haynesworth.
I just want to point out that he played a high number of snaps for a DT. His snap count percentage the past 3 years have been 85.24%, 84.4%, and 83.3%. Compare that to Casey (78.4%/66.4%/79.6%) and some of the other top DT (Aaron Donold-79.1%/76.1%/73.6%, Fletcher Cox-80.1%/75.6%/58.9%, Geno Atkins-72 4%/71.7%/65.8%), and you see just how many more snaps Suh has played.
When you play that many snaps/plays, there's bound to be plays where you're not going to appear be going "all out". My point being it's unfair to Suh to compare him to guys who've checked out after big paydays like Fat Al or to question in effort without knowing a little bit of the background.
