Fans got mad because he didn't put up monster pass rushing statistics but he was never a pass rushing guy, even in high school. One of the things I liked most in his highlight tape was his ability to two gap and not only occupy linemen but get good push.
He was solid if not spectacular here and honestly is better off playing in a system opposite of what Manny Diaz wanted. Asking him to get upfield and disrupt the backfield plays against what he does. He's not tall but he's stout and pretty quick for a 300+ guy. We really could have used him last year. He's better than anyone we had at DT outside of Taylor.
If I remember correctly, he had some issues in the locker room with guys he felt weren't playing hard. I'm sure a bunch of those guys were still here last year so it probably worked out best for him personally to transfer.
Regardless, he left, didn't make a scene and is doing well so I've got no issues with him.
