I don't see the QB play getting a whole lot better, due to good ones leaving. The XFL may be doomed to be the minor leagues for the NFL. Like minor league baseball and D-league NBA. Not much money in it and magnitudes less fan interest. Not sure D-league or minor league baseball could survive financially if they were not run by MLB and the NBA. Will be interesting to see how it goes.
I am all for adding competition to pro sports. I think we have a supply issue, hence the insanely high ticket prices and salaries. Plenty of demand, if the quality is good.
