To be fair to Jim Harbaugh, Colin Cowherd is a professional feces thrower with a national platform, and he's generally bad. I wouldn't want to appear on his show either, unless I were given an unmitigated platform to inform Cowherd of his general badness.
But I am not the millionaire public face of a university and its football program.
Jim Harbaugh appeared on Cowherd's show today, and it was a spectacular disaster. But don't take my word for it:
UPDATE (2:21 P.M.): Harbaugh, always one to be present on Twitter (as Cowherd mentioned in the interview) took to his personal account to offer an explanation:
In my experience of participating in interviews, I've found it takes 2 to produce a clunker! I'll take 50% responsibility 4 this clunker.
