I'll try to summarize all of the comments I have made about this the last couple of days in this thread.
1. I like this as a change of pace and, as @Riverbrian has pointed out, is the wave of the future and we need to embrace it if we want viewership to continue to rise, especially for the Twins are depending on MLB.TV for their production and distribution. As people have developed fatigue for the number of streaming services which they have to pay for, the ability to continually make a production more entertaining is a must.
2. The goal would be to tighten it up, so it is closer to the ManningCast that we see on Monday Night Football. A bit more analysis would really elevate this broadcast, such as a better explanation for why Lee was picked off 3rd last night would have helped.
3. Wednesday's broadcast was already an improvement over Tuesday's as they weren't all in the booth at the same time for much of the game. The idea of getting to have analysts in different parts of the stadium was a great experience to watch and listen to how they see the game from various parts of the ballpark.
4. We got to see first-hand the outsized influence that Plouffe has on the organization. His antic of handing out $20's got Tom Pohlad out of his suite to sit down with both Plouffe and Span in the corners and interact with fans during the game. I challenged this thread to find me another front-facing owner who has done this, in any sport, in the last five years. So far, I have not received a response on this one yet. This isn't to defend the Pohlads in what they have done to this team, just pointing out that he is willing to step down from his ivory tower, even for a moment, to interact with fans. I also believe Plouffe is the only person in the Twins organization with a pulse on the fanbase due to his position with Jomboy Media.
Ultimately, this will be a win for future viewership. I would like to see Molitor in the booth for one of the games, maybe not all of them. I understand the concern of toning down the jocularity as they would defer to him as an expert. I think the broadcast would win though as we would get to hear from both a manager's perspective as well as a player. I think hearing from what the manager expects in a situation vs what the player is experiencing would be a great insight to the broadcast. There are two series which this broadcast setup would be perfect for: this series in front of the Twins HOF weekend and the upcoming Player's weekend, provided the Twins are at home.
