Billionaire booster T. Boone Pickens attends Oklahoma St scrimmage, addresses team

Billionaire booster T. Boone Pickens attended an Oklahoma State football practice for the first time in at least three years Friday.

Pickens hadn't been around, in part, because of a non-existent relationship with coach Mike Gundy. The two spoke amicably while the Cowboys scrimmaged at their indoor practice field, which sits across the street from T. Boone Pickens Stadium.

Pickens, who has donated more than $500 million to the school, blamed himself for the lapse in the relationship with Gundy. Pickens said he's satisfied with Gundy and called him 'a winner.' There has been speculation that Pickens had an issue with Gundy because of his most recent contract, but Pickens said that was never the case.
