A survey indicates many major college football coaches think their peers knowingly cheat in their effort to win games.

Results of the survey that drew responses from 66 of the nation's 104 major-college head coaches queried were reported in a copyright story Sunday by the Rocky Mountain News.Two-thirds of those responding don't want a playoff sytem for determining the national collegiate champion.

Nine in 10 of the respondents say they feel "a great deal" or "much" pressure to win.

Forty-one of the responding coaches said they thought some of their peers knowingly cheat. Their estimate of incidence ranged from 1 percent to 60 percent, with most of the estimates ranging from 5 percent to 30 percent.

"I think (recent NCAA measures) have helped a great deal in terms of major infractions, but they've had very little impact on minor violations," California's Bruce Snyder said. "Everybody pushes the limit. All of us work the rules to our advantage. And in the pushing process, some go over the line."

Many of the responding coaches thought it is up to the coaches to reduce cheating by their peers.
