Veteran defensive tackle Tommy Kelly is a powerful presence at 6-foot-6 and 310 pounds, and plays with what Bill Belichick described as “long levers.” On a “sudden change” situation, in which the Patriots’ defense had to stem the momentum after Brandon Bolden lost a fumble at the New England 19 with 3:21 remaining, Kelly simply powered his way through rookie right guard Larry Warford. Too powerful – the veteran schooling the youngster on how it’s done. With Kelly on the interior, the Patriots have the potential to get more interior penetration in 2013. He looks like a decisive upgrade over last year’s co-starters Brandon Deaderick and Kyle Love.
