He's 4 years older than when he played for the Pats. 30 isn't all that young in NFL years for a D Lineman. His motor may not be running at max rpm these days.
In the last 3 years, he's only been available to play for 18 games, spending time on IR each year. He's played only 33 of 67 games since leaving us.
Rotational use, sure; I already mentioned that. Mentor capacity, however, is full time.
Look at his vet minimum team friendly contract to see how BB views his production value.
Base salary: $1.165 million (veteran minimum with 6 years of service) (incl. only $50,000 guaranteed)
Roster bonuses: $510,000
Incentives: $825,000
Salary cap hit: $1.285 million. More than half his potential $2.5M earnings are NLTBE incentives.
Miguel says he replaced a player at the bottom of the "top 51" and the net loss of cap space amounts to only $365K. That's a team friendly deal if ever there was one.
As I said, I'm hopeful he can play well for us but not optimistic.
