The win earned him one of four contracts dished out by UFC President Dana White on the penultimate episode of Season 2, along with Ian Heinisch , Jordan Griffin and Juan Adams . The desire to win the fight by submission was evident from the opening bell, when Roberts went right after Gross and tried to jump on a guillotine. He got top position through a big takedown and was absolutely relentless from on top. He mixed up ground-and-pound and submission attempts, putting what was arguably a 10-8 round on his opponent.
