Illinois Mascot Reason for No Tourney's

Illinois' mascot has cost the school a chance to extend its seven-year streak of hosting NCAA men's tennis tournaments.

The NCAA's executive committee declined last week to remove Chief Illiniwek from its list of "hostile and abusive" mascots, making Illinois ineligible to host postseason athletic tournaments.

Comment - I just looked up in a dictionary what the word Illinois stems from:

A confederacy of Native American peoples formerly inhabiting southern Wisconsin, northern Illinois, and parts of eastern Iowa and Missouri, with present-day descendants mostly in Oklahoma.

The symbol of Chief Illiniwek is meant to celebrate the namesake of the state. If celebrating the namesake of a state is a violation of NCAA rules, then is not the very name of the state itself improper?
