Here's my take on KNBR throughout the day.
Murph and Mac (5-9am) - definite strong suits for them are talking Giants and golf. They're a morning show, so they often delve into non-sports stuff every now and then. They do have alot of guest interviews though, especially when it comes to the Niners. Frequent shows during the season are the Harbaugh show, Brian Jennings show, and the Ronnie Lott show which is probably my favorite. They panic way too much when the teams lose, and often misinterpret a bunch of stuff. When it comes to wanting any NBA info during their time slot, dont even bother. They have very little to offer in that area.
Damon Bruce and Gary Radnich (9am-12pm) - Fairly new pairing and somewhat interesting seeing how these two mesh. Both had their own shows and I actually enjoyed Bruce's show a bit more. He's definitely a hardcore sports fan, but he often feels himself a bit much. He's one of those guys that'll see a "big-name" available, and vehemently want the local team to go after them. Hard to blame him though since the teams have been pretty lousy for the most part throughout the years. As for Radnich, his shows would too often go into pop-culture, especially during his Tony Bruno segments. Radnich is definitely full of sports "knowledge", but he too often spoke over his callers. You could definitely talk all sports, both professional and collegiate, during this time slot.
Fitz and Brooks (12-3pm) - I used to like these guys, but their style became a bit tiring for me. They both like to attack the callers, and they both feel like they know it all. Fitz will make you think that the Warriors are just as good as any team out there and that Monta Ellis is a top 5 player in the NBA. Brooks for the most part just goes along with Fitz. They do go into all sports with the strong suit being the NBA.
Razor and Mr. T (3-7pm) - They may be the most well-rounded show with the exception of Barbieri's voice. Tolbert is very knowledgeable and often offers good insight. Barbier far too often goes into long questions/statements especially in their guest interviews. They have the Steve Young show during the season, which is a great one. I would probably listen to this show more, but it is on-air at the end of the work day for me and once I get home, its all TV from there. This time slot probably offers the most Sharks talk and their strongest point would be the NBA. But like I said earlier, they are more rounded than all the other shows.
Sportsphone with Eric Byrnes (7-???) - dont really listen cause again I'm watching TV by this time, but I hear he's a great host.
