SALT LAKE CITY — Going undefeated is a difficult thing to do in football and it gets tougher at each level. In college, only a couple make it through unscathed, if at all.

So far this season there are nine teams still fighting to stay perfect. This week, seven battle to remain unbeaten and several will have a difficult time doing it.

No. 4 Washington Huskies (7-0) at No. 17 Utah Utes (7-1)

The biggest threat from keeping the Huskies from going undefeated currently is Utah. The scary thing about the Huskies is how mistake-free their offense is playing, specifically quarterback Jake Browning.
