TEMPE, Ariz. -- Arizona Cardinals defensive lineman J.J. Watt wasn't sure he was going to tell the world he was retiring until he pressed "Tweet" on Tuesday morning.
The future first-ballot Hall of Famer had known for a while that this was going to be his last season, Watt said during a news conference Wednesday that lasted more than 16 minutes. He had been telling people around the Cardinals' building for "a long time" but he doesn't think many believed him. And for those who did, they tried to talk him out of it.
