I saw an interview with Irvin on local (Dallas) TV, and without a script, he can barely put two coherent words together in a row!
It was almost impossible to make out what he was trying to say.
Interesting. I have to say that I've been pleasantly surprised by his unique point of view on the pre-game shows this year. I do think he adds something to the mix. That doesn't excuse his current mess, of course.
