I was thinking almost the same thing. Heyward is getting older so that is why they probably want to definitely keep Tuitt. But, for a couple series when Alualu was in there, he and Heyward along with Bud and Watt were just unstoppable and they didn't need another blitzer. Yes, the Steelers got a ton of pressure with only 4 guys and 2 were OLB's!!!!!!!!!!!! Who would have thought? Hargrave looked OK when in there but I think Alualu hits it faster. I also saw Buggs and his first step is slow as molasses but when he finally engaged an o-lineman, he does push him back ward. He really needs to work on his first step and quickness off the ball.
