I really don't care for much sports talk, though in bed i listen to WFAN out of New York, i have for years so i have developed a liking for the overnight guys....
I can listen to all the ESPN Radio guys except for Patrick/Olbermann, as a poster above said, Olbermann is absolutely terrible, i can't slog through listening to him for more than a minute without switching to NPR...Dan Patrick was good in his heydey, but now he tries way too hard to be witty, being witty and tounge in cheek is only funny when it's off the cuff, not forced or planned.
Jason Smith, well, i'm rarely up in his time slot, but he's decent, as are Cowherd and Eric Kusilias...though every so often they come out with stuff that is just plain stupid..once again, only listen to them when the radio is really dry as far as content on any given day
