But he was much more than a damned good football player. He was one helluva guy. He was kind. He was friendly. And he was a riot. Donovan was to story telling what Jim Brown was to running backs. Nobody told one better. He had a laugh the size of Memorial Stadium and a kind and generous heart -- always willing to help out when and where he could.

"It's a great loss to the league. He was part of those teams with (Johnny) Unitas and Lenny Moore. And our careers just about crossed each other," Eller said. "Just was a great player was a hard worker. Was the kind of a guy I think his teammates got to know him personally and his antics and all of the stuff before the rest of the world did. The rest of the world learned that he really was a fun guy to be around, but he was a great tackle, a great player."
* USA Today's Nate Scott took a look at some of Donovan's best moments on late-night television through the years.
