Last year, he vowed to make every Oklahoma State football home game, but made half of them. “Each trip to Stillwater will be all the more meaningful for me,” he wrote. “Five years ago, as grand marshal of OSU’s homecoming, I knocked out pushups on the ROTC’s pushup board. Now walking 50 yards to my suite is a challenge. And when I do it, I feel just as triumphant.”

One of his greatest memories came 10 years ago, on Sept. 5, 2009, when Oklahoma State  dedicated the fully renovated stadium named in his honor.

“But I’m in it to win it. My first goal for 2019 is to win a Big 12 football championship…again. Then to make the final four playoffs. Fingers crossed Mike Gundy can make that happen this year. The window is closing for me.”

His total giving now stands at $652 million, “a number boosted by a series of unpublicized gifts over the past 10 years.

“I want to see the good that’s done with my money today, while I’m alive, and not wonder what is done with it long after I’m gone.”
