Anyone remember Bill Reed and Jerry Groom?

Reed, the longtime voice of the Denver Bears, and Groom, an All-America center at Notre Dame in 1950, were the first Broncos announcing team on KBTR 710 AM during the initial season of the American Football League.

Fred Leo, a longtime Denver sports personality, replaced Groom in 1961, and Reed then worked with Al Helfer, who had a national radio network background, for two years.

The games then shifted to KTLN 1280 AM with the legendary Bob Martin working with Joe Finan, a controversial liberal talk-show host.

Next up for a year on KTLN: Finan and Joe McConnell for one season.

The broadcasts then moved to KOA 850 AM, where Martin worked for several seasons with Dick Carlson.

When Carlson left to become the radio voice of the Kansas City Chiefs, Martin and Larry Zimmer began a 19-year radio partnership.

After Martin's death in 1990 — he was a cancer victim at age 57 — Zimmer worked mostly with Dave Logan (pictured).

After Zimmer departed, Logan teamed with Scott Hastings and more recently with David Diaz-Infante.

This time journey takes us to the new season that begins Aug. 14 when the Broncos play the 49ers at San Francisco in a preseason contest.

The new KOA broadcasting team: Logan and committee.

Lee Larsen, president and general manger of Clear Channel in Denver, said two months ago that freelance talent Diaz-Infante would not be back because of tight economic conditions.

KOA planned to fill the position internally.

Such thinking evidently has changed, as Larsen now says the likely scenario will be to use a variety of staff talent and "an outsider or two."

Names were not mentioned.

Such a plan is a curious way to provide Broncos broadcast coverage.

A major strength in any sports broadcasting radio booth is teamwork: two professionals working together on a yearly — or a least — weekly basis.

Footnote: Anybody know how Groom, who died in Florida in February 2008, got the Broncos' announcing job?

No one has provided a definitive answer. Speculation is that Groom was a friend of the late Bob Howsam, the first owner of the Broncos.
