He said he was "living his dream" or something to that effect in doing NFL football commentary. Then, he goes and does something so blatantly stupid (in retrospect).
Either (a) he's not as smart as you think, (b) he wasn't living his dream or, (c) he decided to end the dream.
Knowing the way he gushes about football, I think we can eliminate "B" without question. Sounds like you opted for "C" but, I can't eliminate "A".
Maybe he didn't realize that he shouldn't leave half his brain tied behind his back when he comes out from behind the golden EIB microphone.
