I actually think it would be a terrible idea to dump Dennis and Callahan for a couple bloggers, who, from what I gather are just Toucher and Rich without the radio experience.
Currently, they have a strong hold of the older demographic. D and C are not everyone's cup of tea (including mine), but they have their niche, and it is a very large one in the Boston market. If they decide to dump them and go after the 18-35 bracket, which Toucher and Rich have a strong hold of, they are risking losing the market they already have and being completely blown out of the market when they realize T&R fans aren't coming over.
I also like what WEEI did with the Big Show. Ordway and Holley are 100x better than the old format, which was just a bunch of guys screaming at the callers without any substance. Holley does a nice job of balancing out Ordway, and keeping the over the top Big Show fans in check.
Honestly, I think the two stations have found a nice balance. Both have strong (in their own demographics) drive time shows, and both have completely punted the midday.
One this is for sure though, if either of them actually put some money into the midday instead of throwing out bargain basement hosts (you get what you pay for), they would run away with that time slot. Unfortunately, they both know that time slot does not bring in the kind of money the drive time shows does, so we are stuck with the mediocrity we have been hearing.
