I dont watch much of the talking heads but based on twitter if there is one guy i cant stand it is keith law. Olney and rosenthal may be huge cringeworthy nerds but at least they bring something to the table.
Law's a douchey guy at times, but I feel like he brings something to the table. As for my personal list, pretty much everyone ever. There a few good guys on the Yankee beat, but I can't think of a national guy I really like. Ken Rosenthal comes close, I guess.
