I didn't have a problem with Kornheiser since he's at least a sports talk show guy. Miller, better than he got credit for, but still really bad and totally the wrong audience. The other guy after him was even worse, thankfully he only made it two games or so.
I don't get the Ellen thing, I thought it seemed obvious that Paula was done and that's why they brought on the 4th judge this season, to get her acclimated and then go back to 3. 4 judges was a disaster from a timing perspective, its why the shows always ran over, though I guess they like that since it inflates their ratings.
