College football's Davids will get fewer chances to knock off the Goliaths in the coming years.

Part of the fallout of the sweeping changes coming to college sports will be a decrease in so-called guarantee games in football, where a power conference school pays hundreds of thousands of dollars to have a team from a lesser league play at its stadium.

The result will be far fewer opportunities for embarrassing blowouts and startling upsets. Pac-12 Commissioner Larry Scott says he is "not very sympathetic" to the potential loss of revenue to the schools on the receiving end of the checks.

The commissioners of the lower-revenue conferences say losing the pay days won't kill their leagues.
