I know what you're saying with Kornheiser. But, I don't find Wilbon funny and I think he's a goon.
Bubba can be funny. But, he talks out of his ass quite a bit.
I think that the entertainment you're saying comes with comfort and relaxation. I don't think Bubba and Mark are quite as comfortable with each other on-air as off. It could have something to do with Sportsline being live.
I don't like that PTI act like they actually give a shit about Canada. It's clear to see they don't.
