*according to a thoroughly unscientific survey of listeners to the Broncos’ flagship radio station for four hours on a chilly, wet autumn afternoon in Denver.

It started with a Twitter post — a “tweet” — by Roy S. Johnson, one of the better sportswriters of our time. Acknowledging Allen Iverson’s formal retirement the previous evening, Johnson offered his list of the “five greatest 76ers ever.”

His list: Dr. J, Moses Malone, Charles Barkley, Allen Iverson, Wilt Chamberlain.

We substituted “Broncos” for “76ers” and took calls, emails, tweets, whatever, for parts of four hours on 850 KOA.

A margin of error should certainly be built into the results. It’s a small sample size, its demographics unknown, etc. Still . . . here are the five greatest Broncos ever, according to this admittedly approximate methodology:

John Elway

Terrell Davis

Floyd Little

Randy Gradishar

Shannon Sharpe
