Johnny Manziel continues Heisman season with amazing first-half TD run (VIDEO)

It's hard to look like a man among boys in a game between Texas A&M and Oklahoma, but this is Johnny Manziel's world.

The Heisman winner added another clip to his impressive freshman season highlight reel on Texas A&M's first drive of the Cotton Bowl against the Sooners.

He spun away from the rush from his left into the open field. He then juked a defensive back near the sideline, and that's when things started to get interesting.

Manziel somehow took three steps in bounds, tiptoeing the sideline without losing his balance to get into the end zone for a 23-yard touchdown. The Oklahoma players and everyone in the stands at Cowboys Stadium seemed surprised that he actually got across the goal line, because it looked like he was going to careen out of bounds. But this is Johnny Football, and he scored.

In the first half alone, Manziel had 113 yards on seven attempts. He was the Heisman winner for good reason.
