I'm a long-time Baltimore detractor but ... Angelos had Jon Miller and Gary Thorne doing O's games -- two well-respected broadcasters at a level the Nats have not yet even sniffed.
Well, due respect to Carp, but if you want a legacy of broadcasting, try the Pawtucket Red Sox.
Gary Cohen (mets), Don Orsillo (padres), Dave Jageler, Andy Freed (rays), Dave Flemming (Giants), Glenn Geffner (Marlins), Aaron Goldsmith (Mariners), Jeff Levering (Brewers), Mike Monaco (who started in 2020 with the Red Sox) plus the announcers for the Bengals, Patriots, OKC Thunder, Wild, and Bruins. With that record, MASN should just hire either Will Fleming or Josh Maurer.
