I'm not putting the demise of the USFL all on Trump, there were other things that were done by that league that did them in.
Does "O.J.: Made in America" count as a 30 for 30? Because if it does, that is an excellent one.
I also enjoyed "Small Potatoes", "Catholics Vs. Convicts", "Nature Boy", The Baltimore Colts Marching Band, and the one about Jimmy the Greek.
