And he's only going to adress Marty's on-air comments if he feals/has evidence that Marty is effecting the bottom line of the Reds. While some here can make a case that "talking down the economy" occurs due to Marty, unless he really is effecting the teams profits BCast isn't going to put a muzzle on him, and might actually create a backlash were he to do so.
The #1 reason casual fans have stayed away from the ballpark has been because the Reds have sucked. If Marty starts praising Dunn daily, but the Reds still suck, it's not going to convince people to come to the ballpark. Only sustained/consistent winning will do that.
