Program Manager Agnew was so quoted in an article in the SF Chronicle...early '90s IIRC (Sorry, don't have the citation.)
Many of the radio hosts on KNBR under Agnew and Salvadore were of the "provocative" "in-your-face" confrontational type, e.g. Pete Franklin, who shrilly screamed at, personally berated and often "toilet-flushed off the air" callers whose invited opinions he didn't care for. "Nice guys" like local sportswriter Dave Newhouse were replaced when Agnew came along.
I stopped listening to KNBR -- Rick Barry excluded -- after tiring of Ralph Barbieri's whiny tone, grating voice and limp, tedious "sports commentary." (I've also stopped watching cable TV for "news", preferring information, commentary and variety from the actually-up-to-the-minute Internet, rather than the powder-puff, lapdog "news reporters" on corporatist-propaganda-TV.)
Barbieri and Franklin (long gone) are examples of a "negativity is good" style of hosting. And Barbieri would be much less tolerable than he is now, were it not for the saving graciousness and color of added-partner Tom Tolbert.
I don't know much about Krueger, but I appreciate Alou coming down and speaking out on his cynical, unreflected, sloppy comments that were inspired, in all likelihood, from an attempt to "draw audience interest" using the negativity technique rather than made from any direct racist intent.
While I didn't catch Tuesday morning's apparently-bad-taste "comedy bit", nevertheless I suspect Bob Agnew's firing was less for having a "sacrificial lamb" -- as Radnich suggested -- and more for demonstrating an actual substantive rejection of the negativity-is-good philosophy that may have underpinned Krueger's comments...as well as those of many other KNBR hosts over the years.
Alou: 'I feel bad about people being fired'
