I would be a bit leary of selling Stanford short after last night's game. I'm sure when they were having their way, up 13 at the half, some of their focus shifted to the Arizona game.
Over the past 5 years (as gjn pointed out), Stanford has given Zona an extremely tough time in Tucson. For whatever reason, they just seem to bring their 'A' game when playing there.
Stanford beat Gonzaga and Kansas on neutral courts (without Childress playing), won at Irvine and Rice (which are solid wins), and besides last night's game have handled everyone else convincingly.
Zona struggled to win at St Louis (good team but you wouldn't expect a 1pt nail-biter against them) and had all the could handle at home versus St Mary's and UL-Lafeyette...two decent teams, but again, you wouldn't expect Zona to struggle so much against them especially at home.
Zona has the ability to blow any team in the country out, but again, I wouldn't sell Stanford short on the basis of one game, which they did end-up squeezing out.
