BostonSportsMediaWatch says that Dennis will be co-hosting his show with Arnold and possibly Holley (while
Callahan's voice recovers?) Could this be a tryout in case Callahan leaves...?
see:
"What's the rationale for having Arnold moved to the mornings for the week? When you consider that WEEI also tried out Dennis with Glenn Ordway for the Sunday morning draft program last week, you see some tinkering, some experimenting with combinations going on over there. Is this in preparation for the possibility that Callahan doesn't come back - either because his voice doesn't recover or he decides to sign on elsewhere at the end of the summer?"
