Dave O'Brien, Dennis Eckersley, and Jerry Remy are calling the Red Sox tv games from the NESN (New England Sports Network) studios in Watertown, MA. I watched all 3 games over the weekend plus 2 spring training games last week. Several times, they showed the guys in the studio, socially distanced, and separated by plexiglass. They each have their own monitor in front of them and there are apparently several other monitors they are looking at as well. Jerry Remy's health (his previous bouts with cancer) was a big reason they are keeping the guys away from Fenway plus, as already mentioned in this thread, only a certain amount of media is allowed at the ballpark. Sideline reporter, the very lovely Guerin Austin, is the only NESN member at the ballpark during the game. She is somehow finding things to talk about.
For me, I've had no issues watching the games. The 3 guys and Guerin have done a really good job. Sounds like they are at the ballpark.
I did see part of one of the ESPN games yesterday and there was a huge difference between them and NESN. It actually sounded like they weren't at the ballpark and there was a noticeable delay between the guys talking to each other.
NESN is broadcasting 55 of the 60 Sox games with ESPN and Fox picking up the other 5 games.
