I believe that in spite of the intensity of the OU-OSU rivalry, Stoops and Mike Gundy like and respect each other.
I think it's also possible that OU did not want its defense or kick return team on the field again, even with seconds remaining. It was a very physical game with numerous injuries....maybe the coaches on the OU sideline decided enough was enough.
Whatever the reason or reasons for Perine taking a knee, I think it reflects well on Stoops, his staff and his team. Such a display beats the hell out of the frequent pre and post game taunts and threats and the on-field hostilities akin to prison yard warfare, which so many fans take delight in.
I want to see games decided by skill, coaching, planning and execution....not by rotten, stupid, narcissistic conduct.
According to Stoops in the post-game press conference, Perine made that decision on his own. And he was in full support of it.
