Those numbers were as a Sub, not a starter. He also lined up 139 times on the END, not at DT last season. If you look at his time in Minnesota and Chicago, his ratings were poor. I
The Pats could see him the way that BB saw Vrabel in 2001. A guy who wasn't used enough at a particular position. Watts HAS experience as a NT having lined up there in Minny and Chicago. And he's about the same size that Godchaux was when Godchaux originally signed.
Watts, when he was signed, was thought to be a reserve Pass-Rushing DT who is an upgrade over Pharms/Roberts and could spell Wise/White. With the experience he has across the D-line, he could potentially be a reserve for Godchaux.
Until we see how Watts does in the Pats system, we don't know what he brings. A perfect example of that is Mike Pennel. Pats brought him in with high hopes and he bombed out. Pennel has since bounced around and landed with the Chiefs on 2 different occasions and has 2 rings to show for it.
