Those Featherweight and Middleweight tournaments were pretty awful. Those two divisions need a complete talent overhaul IMO. Welterweight just had too many cookie-cutter wrestlers. Lightweight was just meh.
I hope this two-fights a night thing is only for this season as they had to start in the summer. Too many tentative fighters on those tournaments. If the season starts in January next year, maybe the fights will be better.
Their most entertaining divisions were easily Light-Heavyweight and Heavyweight and those divisions weren't stacked in the slightest. They just seemed to have the most fighters with nothing to lose. Besides Vinny, I doubt any PFL talent at LHW/HW would be top 15 in the UFC.
