Understand this: I am not pining away for the days of Glenn Geffner, but I have to admit that there is a noticable lack of energy when Dale Arnold straps on the old microphone as he did last night with Joe C.
Listen carefully or absent-mindedly, it sounds like The Church Lady is calling a game when Dale has the mike. I think the problem has to do with the pace of the game. Unlike hockey, with which Dale has a lot of experience, a baseball game does not create its own energy. Think of a ball game as a modulating wave. Some announcers (see e.g. Dave O'Brien) carry the call slightly above the wave, and increase intensity when the natural energy of the game appears.
Some announcers (see e.g. Joe C) talk in the pocket of the modulating wave, carrying on a conversation. When the wave increases in intensity, the announcer raises the pocket.
Dale is sort of independant of the underlying wave. He's not bad, but his call sounds like an overlay of the game, rather than being part of the game.
Your mileage may vary, and he is still an improvement over last year, but there is something missing at this early date. Given the fact that we as listeners have to bounce from one style to another, depending on whether Obie has an ESPN assignment, it is a bit frustrating.
