With the Patriots practicing in full pads the last two days, fullback James Develin’s hard-charging, lead-blocking presence has been hard to miss. Develin, who graduated from the practice squad to the active roster in 2013, brings an attitude to the running game and was praised by personnel director Nick Caserio for having a “great offseason.” Ridley also pointed to Develin when asked about the overall running back group. “Not to single out one guy, but James has come in and done an awesome job,” he said.
