I am actually starting to come around a bit on the Sports Hub's morning show. They still annoy me a bit, but they seem to be getting better about not driving their bits into the ground, and seem to be figuring out the sports talk thing a little more. They no longer sound as much like cheap Howard Stern ripoffs, pretending they know something about sports.
As for Pete Sheppard, I am not sure he would really be the right pickup for them. It might stick it to WEEI a bit, but I think it would hurt them with their listeners. I think most people who listen to 98.5 do it because they are sick of the "yell over the callers" persona of WEEI, and Sheppard is one of the biggest offenders.
I think they have a couple very strong shows right now with Felger and Mazz (my favorite show...they balance the over the top opinions with rational discussions better than anyone), and Zolak and Gresch (two excellent football guys...although I have no interest in hearing them talk about anything else). And the morningshow is decent enough to get people to listen to it when they don't want to hear about those "dingbat left wingers". No need to rock the boat by bringing in such a big personality like Sheppard, just to needle the competition.
