Morning shows are morning shows, so you either like them or you don't. It's not all sports. I'd take D&C over the competition, but neither makes me get up and set the radio to their station.
10-2:
Dale and Holley offer some actual insight along with commentary, and they can do that with multiple sports. Zolak is ok for football, since he knows the "x"'s and "o"'s as a former player, although he still screws them up on occasion (helps explain why he was a backup) and Gresh is just a buffoon.
2-6:
The Big show offers multiple opinions, with various former players in Baseball, football and basketball, along with journalists and columnists. It's a rowdy approach that generally follows a bit of a homer bent, and it generally offers much more knowledgeable insights than Felger/Mazz. Felger/Mazz features one man who's a crap stirrer rather than an honestly opinionated person (Felger), and another man (Mazz) who rarely takes a break from ballwashing Felger to offer any deep insight of his own.
6-whenever:
Mike Adams just doesn't strike a chord with me. D.A. is the only decent host/co-host on the entire 850 team, and is worth listening to if you're out on the road.
From 10am - 6pm, I strongly recommend listening to WEEI, with commercial drop-ins to the other station. At 6pm, switch to 98.5. That's the best way to go if you're a sports talk fan. It should keep your hostility levels low, and it offers you the best programs at the same time.
