Honestly, probably a 6 or a 7. There were some good fights, but the 3 main fights were completely uncompetitive. The only saving grace was that one of those total blowouts was a completely unexpected upset.
Hell, come to think of it, was there a single truly competitive fight in the main card or televised undercard? I can't recall one. A night of pretty one-sided fights. No way I can call that a 9 or a 10. I think a 6/7 is being generous. The huge upset in the main event was really the only saving grace.
