Ditto - same here (1977 alum) but I see it another way. This was really just another form of rubbing it in, just appearing to be merciful when doing it, IMO. If Perine earned that TD (and he did), then he ought to get it. If OSU football players are offended by "running up the score," then their choice is to get better and get a coach that doesn't crap down his leg nearly every time he plays OU (2-10 record during Gundy's tenure.) Even The Mad Hatter, Les Miles, beat that percentage.
My older son was/is a take no prisoners jock.
He agrees with you.
