Well I've never heard of a football team named after Crayola, but if there is, then wouldn't it be named Crayola? :)
J.E. Clair named his football team Green Bay Packers.
University of Tennessee.
The new york jets.
I have heard that the Seattle Seahawks had been named after the actual seahawk. The Seahawks are the ONLY National Football League team in the entire nation to have a live mascot!
They named the team "Mean Machine"
