My stream of consciousness $0.02...
Ward was one of the top hosts for some time, then he grew stale. It seemed like he got lazy and each show focused on a single news story or headline. I guess that works for a 3 hour show where drive time was 15-30 minutes per listener. His MIL picking football games was good radio.
I am not sure how Ed Clements is still on the radio. Seems underprepared and is mailing it in - and has been this way for a decade. That said, he was a decent foil for Ward when they worked together.
Babers has dramatically improved over the years. He does his homework. However, he throws out tons of stats and data to catalyze conversation. However, data != information. I'm exaggerating, but he'll pull out some stat like "Last year, Texas was 6-7 on third downs following an opponents time out in the third quarter when down by a touchdown and preceding a Ford commercial." Uh, OK.
I've always enjoyed Bucky on the radio. And, for the most part, he has ALWAYS been unprepared (or at least underprepared). For some reason, it did not bother me. He had enough personality - and Erin was always prepared - that it did not matter.
Dudley and Bob was pretty decent radio in the early 90s. I think Dudley took a major turn for the worse when Howard Stern's syndicated show was added to the Austin market. Dudley lacked Stern's wit and his interviewing capabilities. He tried to match/beat Stern and it made his show uninteresting. From that point, the show stagnated.
Going even further back, there was Dave Jarrott on K98 and KEY103. He brought fake commercials and parody bits to the market in the 80s. Recall the "Hiney Winery" in Pflugerville? And the wine-colored velvet-covered couch...
