SPOKANE, Wash. -- Washington State coach Bill Doba and his assistants think they have figured out a way to stop No. 1 Southern California.

"We agreed the best place to attack 'em is in the tunnel before they get out on that field. At least that way, Reggie doesn't have as much room to run around, see, and we can corral him in there," Doba said of Reggie Bush, USC's all-everything tailback, as Washington State prepares to play on the Trojans' home turf.

The Trojans (7-0, 4-0 Pac-10) last season's national champions, have won 29 consecutive games, including 23 in a row at home and their last 19 Pac-10 contests.

"How do you beat them? Ask those other 29 teams they've just beaten," Doba said Tuesday in his weekly teleconference from Pullman.
