Pay no attention to that man behind the curtain
Aren't you guys getting ahead of yourselves? He is signed through 2016 with the 2017 5th year option available. You have 2+ season to see if he can sustain his production before a long term commitment. And even then, you could tag him for 2018 & 19 into his age 30 season with no long term commitment.
I know it seems odd to an outsider. People on this board are all about overpaying overrated defensive lineman. Dont bother trying to bring common sense into the debate. That will only irritate them.
