About a year ago, I was hired by a Cleveland company to do some work for National City Bank. 
They needed a mascot designed that could appear at bank openings and events. They had some concepts, even some rough costumes, and needed them converted into a cartoon. Kind of like taking the Mickey Mouse you see at DisneyWorld and from that making him a cartoon. My initial designs can be seen here.
From there, we went through many revisions. Quickly the deer, or "Uncle Buck" became the favorite. He went from being an older uncle to being an older coach to being a younger coach. Briefly, they flirted with the idea of giving Coach Buck a younger buddy, Junior Buck.
The final design implemented a number of changes and revisions. Many cartoon characters like Donald Duck and Porky Pig wear shirts but not pants (except for when they come out of the shower for some reason) so that was the convention I used. The decision was later made to give him pants. And his antlers were turned from regular antlers into dollar signs. He also went from an older, pudgy design to a much younger, fit design.
Coach Buck has appeared mostly in the Chicago area. He's made some personal appearances and been available as a coloring page, too.
