Not trying to be critical, but the truth is the truth. Tyson Alualu (pronounced AH-loo-AH-loo) is no Stephon Tuitt, the man who's production Alualu is being asked to help replace. Tuitt was having his best season prior to his injury, consistently being a disruptive force.
Tuitt has always had the superior athleticism needed to be one of the best defensive ends in the NFL, but durability has been an issue. Sadly for Tuitt, availability is one of the greatest abilities. Luckily for the Steelers, Alualu is nothing if not reliable. In no way exceptional, Alualu is a pro's pro.
