Tywain Myles left Nacogdoches as a fullback and defensive end. He enters the N.F.L. as a defensive tackle. The Tarleton State lineman was not drafted this weekend, but did sign a free agent contract with the Tampa Bay Buccaneers. The former Dragon had six sacks in his final collegiate season. He'll try to grab a spot on one of the N.F.L's top ranked defenses.
