I'm torn on this one.
I'll always applaud trying new things and I certainly wouldn't call this any sort of failure. It was fun and novel. I think day 2 worked better for a couple reasons.
a) Having 1 day under your belt helps
b) It wasn't all 4 of them in the booth the whole time. 4 in the booth was too many.
It's interesting, I think this is a better format for some of these guys and a worse format for others. I think this was better for Plouffe and Morneau. For Plouffe it was his natural environment. For Morneau, I think he's a very thoughtful guy with good stories and analysis, but my biggest knock on him is that his stories become novels and his analysis drones on. This format doesn't allow that and I think that was good for Morneau
For Perkins, I think he's really good ay being the 2nd guy in a 2-man booth. That's his sweet spot. Of these 4 he's the best with Provus (IMO) but also of these 4, he'd probably be the first guy I'd pull out of this 4-man booth.
For Span... he's got the least experience of all of these guys (by far), so I think he's still figuring out what kind of broadcaster he will be. I thought he did a fine job, but getting this specific type of experience isn't going to allow him to hone his craft.
At the end of the day, my biggest complaint is that they completely lost track of the game at several key points. I don't mind you wandering away to talk about Hacky Sack or Lord of the Rings if you can bring it back to the game when you need to.
Yesterday there was a point where they didn't know Cleveland has made a pitching change. Not great. Then in the 8th inning when Cleveland was walking our entire lineup, one of them was like "oh... man.... we just tied it up." I don't need them locked in for 9 innings but I need them more locked in than they were. The Manning cast works as "not very locked in to the game" because if you're someone that wants a traditional broadcast, you can just flip over the ESPN's main feed and also, when things get amped up in the game, they DO lock in.
So, as a one-series thing? Sure. Fun concept. But I'd make a few tweaks.
