The Lions have begun discussions with the Chargers about acquiring cornerback Antonio Cromartie, a league source told NFL.com on Sunday. The Chargers have been shopping Cromartie, but there had been little interest until the Lions reached out. "It may be time to move on," Cromartie said recently. "I have complained to the coaches about certain stuff, about the way we play, and they know that. But if it's time to part ways and that's in the Lord's will, then that's what's got to happen. But I would love to continue to finish out either my contract or my career in San Diego."
