Antrel Rolle does not want to go anywhere, but he’s a realist. He’s seen many of his Giants teammates walk out the door the past few years, never to return. He’s entering the final year of his contract, and, while he hopes this isn’t his last go-round with the Giants, he knows it could be. “If this happens to be my last year with the Giants, it will be my best season, so I’m gonna go out with a bang,” Rolle said Wednesday on SiriusXM’s NFL Radio. “But hopefully it’s not.” Rolle, 31, believes he has four or five more quality seasons in him. Do the Giants agree? He will make $7 million this season and the Giants have not approached him with an offer for an extension, though Rolle has shown himself to be remarkably durable and one of their best defensive players, if not their best. On Tuesday, when he met with reporters on the second day of offseason workouts, Rolle did not want to vault himself into a heightened position of leadership. With the other defensive captain, Justin Tuck, now with the Raiders, Rolle inherits solo ownership of the captaincy, but he did not state he would assume a larger leadership role.
