BOISE, Idaho — Boise State can finally focus on Hawai'i.

For weeks, the No. 17 Broncos have been quizzed about looking beyond lesser opponents to Friday's matchup with No. 13 Hawai'i, a game that will decide the Western Athletic Conference championship.

Boise State (10-1, 7-0) put itself in position to win its sixth straight WAC crown and maybe earn a second straight Bowl Championship Series bid by dismantling in-state rival Idaho, 58-14, yesterday.

"I'm not really going to think about it until tomorrow," Bronco safety Marty Tadman said of the showdown with the undefeated Warriors in Honolulu. "I think I'll enjoy this victory today. I am really glad now we don't have to keep saying 'We're not overlooking anyone.' "

The Broncos broke open a close game in the second half, scoring 41 unanswered points after the Vandals cut the lead to 17-14 late in the first half.

Taylor Tharp led the way, throwing for 282 yards and four touchdowns, including a 58-yarder in the third quarter to Titus Young that extended the lead to 38-14. Tharp was 22 of 31 before leaving early in the fourth quarter with the game well in hand.

Ian Johnson carried 21 times for 109 yards and two scores and Austin Pettis had eight catches for 139 yards and three TDs. The Broncos rolled up 556 total yards, played their third straight game without a turnover and beat the Vandals (1-10, 0-7) for the ninth straight time.

SEATTLE — Washington didn't need quarterback Jake Locker, after all.

Rankin did not play the final 1 1/2 quarters, apparently because of an injury. His backup, freshman Brandon Johnson, ran for 121 yards on 23 carries.
