I love Kornheiser, but he just wasn't as good as I had hoped he'd be on MNF. He's clever and quick witted, but so much of that show is scripted that I think he never figured out where to just be himself. In between all the talking points, the outlined player profiles and scheme analysis. It seems like it should be far more natural to announce a game than I think it is these days.
Hopefully he comes back to the radio. He had one of the great sports talk radio shows ever.
