Dhani Jones is a average starting caliber 4-3 WILL linebacker who I beleive was a Safety in college. h eis at his best in coverage.
Does he fit the Pats? Not a as a full timer as he was available from the Giants before Philly got him a few years a go and BB passed. But that was when BB had his situation substitute "coverage LB", and one of the best in Don Davis.
Don retired, after his knee injury put him on IR. If he hadn't been injured last year, I am fairly certain that the AFCCG turns out differently, if he was there to do his thing.
I think that "Mr. Bowtie" could easily fit in as a situation substitute in the Patriots reserve LB corps. He certainly is a classy Harvard type dresser.
