Rydalch led BYU with 22 points, scoring seven points in the second half before fouling out in the final minutes.
"I think we made too many mistakes on defense, and then we just didn't make enough plays at the end of the game," said Rydalch, who was 8 of 17. "I think we fought back hard. We made a nice little run in that fourth quarter, but things just didn't go our way."
BYU coach Jeff Judkins echoed Rydalch's thoughts, saying the Cougars were a play or two from advancing to the second round.
"Right at the end we just couldn't make enough plays," Judkins said.
