I think that (plus the eye candy) is exactly what worked so well. A moderator (with some football knowledge) keeps the show on track, instead of 4 'experts' trying to talk over each other.
I still think the show was tons better with the original lineup, even with all the guests in Nate's chair it was better than now. To me Erdahl is fine but still tries way too hard to generate excitement/wackiness that just isn't there - its better when things appear natural.
Just don't like Mccourty at all. To me he brings the whole thing down. I think 90% of the guests host in that chair before the new lineup was picked were such a better fit. That choice just mystifies me, just don't see what they saw in that guy as a fit for this show. The best shows IMO with this new lineup were when mccourtey was out with his appendix and O'Hara came in. It was like a breath of fresh air - so much better and so much more like the way it used to be
