I didn't read his letter as an attack on athletics. It does raise some good questions, and I think it calls out local reporters. He just wants to see the proof in the numbers that there is return on investment in our athletics department.
Maybe its me,but refering to the Athletic Department as the "Athletic Kingdom" in kind of an attack.
As far as "shut up and teach" ,the letter says he's a Professor emeritus.
As far as I know "emeritus" means retired,but with an honorary title.
So he doesn't have to teach anymore.Just sit back,relax and write letters to The Post.
In response to "Ohio cat fan" I think the last sentence in his letter was meant to cynical/sarcastic.Although at least he thinks enough of O.U. to wear an O.U. hat.
