The Vikings hadn't faced a ranked opponent since December 2009, when they beat rival Portland, which was No. 25 at the time.
"Look at their three guards, they've got three or four inches at every position, so we had a mismatch from the beginning," Vikings coach Tyler Geving said. "They'll probably be playing most games in the Big 12 with a size advantage and they have a size advantage on the perimeter playing defense, you can see why they are so good that way."
The Cowboys climbed into the Top 25 this week for the first time since 2007, following a perfect run through the Puerto Rico Tipoff and an upset of then-No. 6 North Carolina State in the tournament championship game. The game marked the first time Oklahoma State has been ranked in Ford's five years as coach.
He has even higher hopes, though, expressing disappointment that his defense relaxed in the second half as Portland State shot 48 percent, compared to 31 percent in the first half.
"The percentages in the second half for them were not where we want them. We have goals to reach and that's not where we want them," Ford said. "But for the game, they're not bad."
Brown and Philip Jurick came up with blocked shots on two of Portland State's first three possessions and the Cowboys raced to a 14-3 lead, with Smart setting up a right-handed dunk by Brown and a two-handed slam by Kamari Murphy.
The dunks kept coming as Oklahoma State's lead continued to grow, with Kirby Gardner lobbing to Brown for a two-hander coming out of a timeout. Smart then set up three straight baskets — dunks by Brown and Jurick and then a Brown 3-pointer — during a 7-0 stretch that pushed the Cowboys' lead to 31-12 with 6½ minutes left before halftime.
"I felt like we left a lot of points on the floor tonight. I told our team we probably should have scored 100," Ford said. "That's not getting greedy or anything."
