If there is a surprise veteran cut on defense, it will be Tommy Kelly. The veteran defensive tackle is coming off a torn ACL after being limited to five games last season, is 33 years old, and restructured his contract in the offseason. That’s a three-pronged combination that makes us feel like he’s anything but a sure-fire lock to stick. Kelly was excellent in the few games he played last season, stayed in Foxborough throughout the year to rehab, and expressed optimism about his health in spring camps.
