TUCSON, Ariz. (AP) -- Colorado prepared for Boston College tailback Cedric Washington. Too bad BC didn't do some homework on the Buffaloes' Cortlen Johnson.

	Boston College's Brian St. Pierre has the ball knocked loose by Colorado's Justin Bannan.

Johnson had a career-best 201 of Colorado's 365 rushing yards and scored two touchdowns in a 62-28 rout of the 25th-ranked Eagles on Friday in the Insight.com Bowl.

"I can't take all the credit," Johnson said. "The offensive line did a great job of opening up the holes, and the wide receivers were blocking well downfield."

Boston College (8-4) was unable to overcome Colorado's speed.

"I think that's one of the fastest linebacker and DB corps I've played against," said Washington, a 1,122-yard rusher who was held to 30 yards in 16 attempts. "The holes were closing up like that, in a second."

Johnson had 34 yards on Colorado's first drive to set up his 10-yard scoring run, then contributed 30 yards in the second possession, which ended with quarterback Mike Moschetti's 2-yard TD.

Johnson gained 40 yards in three carries before his own 2-yard scoring run that made it 42-7 with 5:59 left in the half.

A sophomore in his first year as a starter, Johnson had 137 yards in the first half, more than in any game of his career save the 185 he gained against Iowa State.

"I was surprised we ran the ball as well as we did," Colorado coach Gary Barnett said. "Coltren really started to turn it on as the year went on. He kept looking better and better his last five or six games, and we became a better team."

"At the half, we agreed that we were going to take it one play at a time and play physical," Boston College coach Tom O'Brien said. "We knew there wasn't going to be much opportunity to come back by halftime."

Ben Kelly set an Insight.com record with an 88-yard punt return, and the Buffs (7-5) scored on interception returns of 29 yards by Jashon Sykes and 21 yards by Rashidi Barnes.

It was Colorado's sixth consecutive postseason victory, the longest active streak in the country.

The Eagles got their first TD on a 78-yard interception return by George White, and the last on a 9-yard return of a blocked punt by Doug Bessette with 5:55 to play.

Boston College also scored in the third when William Green fumbled into the end zone on a 1-yard run, and tight end Bryan Arndt recovered, and late in the game on a 2-yard pass from Tim Hasselbeck to Jamal Burke.

The most one-sided result in the bowl's 11-year history was Kansas State's 52-17 victory over Wyoming in 1993.

The Eagles were on their heels from the start after Moschetti came out throwing a 14-yard completion Marcus Stiggers, and the Buffs scored on their first possession for the fourth time this year.

The outcome still was in question when Moschetti dropped back, then ran in untouched with 1:47 left in the first quarter, making it 14-0. Sykes, a linebacker, scored 30 seconds later when he picked off Hasselbeck's attempt to arc a screen pass to tailback Cedric Washington.

White cut Colorado's lead to 28-7 with his scoring return 4:13 into the second quarter, but Johnson gained 40 yards in three straight carries to score his second TD and Jeremy Aldrich sent the Buffs to a 45-7 lead with his first field goal 27 seconds before halftime.

Backup quarterback Zac Colvin scored on a 4-yard run seven seconds into the fourth quarter, Roman Hollowell took a lateral 18 yards for a rushing score, and Aldrich kicked a 21-yard field goal.
