Chris Landry disagrees, and says he is a NT in a 43 (shade or on the nose), and a 5 technique in a 30 front.
Here is the link.
But his site is a pay site, so it may not work for you. I've been a member for a couple of years. And these reports are not written, they are mostly verbal podcasts for members to listen to.
Oh, here is his credentials-
You're not the first person to say this, but I don't know where it's coming from?
Jeffrey Simmons.... is not a Nose Tackle. He's a 3-tech.
Not sure what position he played for Mississippi State, but he projects as a 3-tech at the next level. Exactly like Quinnen Williams, who played the Nose for Bama this year, but at 303, will play the 3-tech on the next level. I've never heard otherwise for either player....
I see that you've cut and pasted material from Chris Landry saying he likes him as a Nose.... I just find it baffling....
