That's the whole point.
Roughly 2800 times I sat down with Tommy to broadcast a game. Every time it was special. HOF player...HOF coach...HOF partner. Celtics Nation has lost its finest voice. Rest In Peace my friend. It has been the privilege of my professional life to be the Mike in Mike & Tommy.
