SEATTLE (AP) -- On the first day of fall camp a year ago, Chris Polk still didn't understand all his assignments or what exactly Washington coach Steve Sarkisian wanted out of his starting tailback.

By the end of the season, Polk figured it out, running for more than 1,100 yards.

On Monday as Washington kicked off its fall camp, Polk was sprinting around with ease, making sharp cuts and racing on the Husky Stadium turf now confident in his understanding of the Huskies system.

Now comes transferring that comfort and knowledge with the Huskies system into production on the field. Monday was the first of Washington's practices that lead up to its Sept. 4 opener at BYU.
