Boise, Idaho ? A cold, wet and dreary morning turned into a delightful afternoon for Boise State.

The weather didn’t improve, but it hardly mattered to the Broncos as they beat Iowa State 34-16 Tuesday in the Humanitarian Bowl.

“The conditions were kind of tough in the first half, but later on they didn’t become a factor,” said Brock Forsey, who ran for three touchdowns to lead the Broncos. “In fact, we played better.”

Forsey, who scored on runs of 4, 2 and 9 yards, finished the season with 32 touchdowns, the second-highest season total in Division I-A. Barry Sanders has the record with 39 for Oklahoma State in 1988.

With temperatures in the low 40s and a steady rain falling, the conditions were hardly typical for a bowl game. It didn’t discourage 30,446 fans, nearly all of whom showed up to cheer on the Broncos (12-1).

Boise State won its third Humanitarian Bowl in four seasons. The Broncos also won it in 2000 and 1999. The Western Athletic Conference champions went 7-0 at home this season.

Bobby Hammer was voted MVP of the game after he had 10 tackles, including three for a loss.

“It was a dream season. Can’t describe it right now,” Hammer said. “We set goals high. But we wanted to do more than set them. We wanted to achieve them.”

The Cyclones (7-7), who opened the season at 6-1 and reached the top 10 for the first time in school history, had a 1-6 finish.

“It was not a disappointment to me. It would be only if you let it be,” Iowa State quarterback Seneca Wallace said.

Wallace hyperextended his knee in the first quarter and missed a couple of series. The Cyclones’ offense never recovered.

Iowa State's Michael Wagner is piled on by Boise State defensive players. The 18th-ranked Broncos stampeded the Cyclones, 34-16, Tuesday in the Humanitarian Bowl on the blue turf in Boise, Idaho.

“We had a good stretch of games,” Wallace said. “I don’t know if we ran out of gas or what. We just didn’t have the fire we did in the first part of the season.”

Boise State scored at least 34 points in each of its victories this season. The Broncos needed only half that as they shut down Iowa State.

Wallace, the Cyclone quarterback who was an early Heisman Trophy contender, had been averaging 268.6 yards of total offense. He had 190 Tuesday, most of it coming after Boise State already had taken command.

Iowa State’s loss dropped Big 12 Conference teams to 3-3 in bowl games with No. 8 Oklahoma and No. 9 Texas still to play.

Three Iowa State starters were ruled ineligible for the game because of low grades. They might not have been much help as the Cyclones battled a boisterous crowd in Bronco Stadium all day.

“We expect our kids to hold up whoever’s in the lineup,” Iowa State coach Dan McCarney said. “We’ve got plenty of guys on our team. Plenty of depth and plenty of players on our team that could play better and should play better.”

The crowd was at its loudest to start the second half with the Broncos trailing 10-7.

Boise State forced Iowa State into going three-and-out on the Cyclones’ first four possessions of the second half, and the Broncos capitalized with two touchdowns to take a lead they would not relinquish.

Ryan Dinwiddie completed passes of 11, 17 and 16 yards to Billy Wingfield before Forsey scored from 2 yards to make it 14-10, ending a quick drive that started at the Boise State 46.

After a punt set up the Broncos at their own 49, Lou Fanucchi took a reverse 25 yards to help set up Dinwiddie’s 1-yard TD run that put the Broncos up 21-10 with 4 minutes left in the third.

Forsey, who had 24 carries for 78 yards, added a 9-yard TD run in the fourth quarter and Dinwiddie threw a 3-yard TD pass to Fanucchi with 27 seconds left in the game. Dinwiddie was 17-for-32 for 160 yards and ran for a touchdown.

“We probably there at the end could have taken a knee and been good, but that’s not the way we play football around here,” Boise State coach Dan Hawkins said. “That’s not our deal. We’re going to attack. We’re going to keep going.”

Wallace missed two series after getting hit on the left knee in the first quarter as the Cyclones drove to the Boise State 13. Backup Cris Love and the Cyclone offense went backward on the first two plays, and Iowa State settled for a 30-yard field goal by Adam Benike.

By the time Wallace returned, the Broncos had taken a 7-3 lead on a 4-yard run by Forsey. Iowa State regained the lead on a 6-yard touchdown pass from Wallace to Jamaul Montgomery with 2:29 left in the half.

“I felt all right. I just went out and tried to do what I could,” Wallace said.
