Teague's most famous moment might be when he decked San Franciscos Terrell Owens, as the 49er wide receiver celebrated a meaningless touchdown atop the 50-yardline star in Texas Stadium.
I think the play occurred in a bowl game back in the early 1990s. Alabama's defense jumped offsides on a play down near the opposing 10 yard-line, so the opposing QB aired a long pass on the "free" play. He completed the pass to a receiver streaking down the sideline. Teague, who was playing safety in the middle of the field and wasn't involved in the coverage, eventually ran him down from behind after a long sprint of 60+ yards. The receiver fumbled the ball, Alabama recovered, and ran it back a long ways up the field.
The opposing team simply declined the penalty and got a 5-yard gain out of one of the most bizarre plays I've ever seen.
