One of Tags' first acts as Commissioner of the NFL was to strongarm the state of Arizona into adopting a MLK Holiday. In 1990, the state held a referendum, wherein the voters rejected adding a MLK holiday to the official state calendar. Tagliabue threatened to withdraw the then-upcoming Super Bowl to be held in Tempe.
The NFL was not the only blackmailer: all media outlets, along with several large corporations, bashed Arizona. But the NFL, led by Tagliabue, led the way. And it was probably the blackmail by the NFL that made the difference in Arizona finally relenting.
If there is a hell, Tags will rot there for eternity.
