Stewart Bradley is pushing Nate Irving for the Broncos' starting middle linebacker job. Bradley actually started Thursday's preseason opener against the 49ers, recording six tackles while playing most of the first half. "We'll take a hard look at the tape and see who executed the best in the game situation and move from there," said head coach John Fox. Neither player really stood out, and we don't expect the winner of this battle to have much IDP value this season.
