I don't mind Ruben. Kruk is fun/funny but beyond that, is more about the stories than game insight. IMO Ruben has come a long way in terms of analysis, and he is not as dull as Ben. There's talk of him going back into someone's front office (not ours), we'll see.
I prefer Frantzke too but he belongs on the radio. He also seems a bit more muted w/o his usual partners.
I actually don't hate Murphy as a PBP, he has the voice at least. But so does Jim Jackson.
