I gotta say from watching Shaq, he looks like a 4-5 sack per year kind of player at best. He is good in setting the edge but doesn't really offer any pass rush. I was watching him a lot in pre season and against the Jets, and he never really has any counter moves with the OT. He just engages with the OT and stays put. Maybe it's his first assignment on the defense to set the edge and his secondary objective to rush the passer. But all in all, he kind of reminds me of Chris Kelsay
