Both Jones and Bader entered as young, can't-miss prospects on the cusp of top-contender status. There was talk of Jones being UFC's next big star, but many observers believed the 12-0 Bader was the right guy to test that rationale. The opening round was competitive, though Jones took it by winning the striking battle. After tasting what Bader had to offer, Jones' confidence soared in the second, landing several strikes before taking the wrestler down and submitting him via guillotine choke to land a title shot.
