The prelim debacle was a pain in the ass but that's not their fault. NBCSports played a much larger role in that decision.
The fights themselves were very good. Several upsets and a few spectacular finishes. That reversed heel hook that Cavalcante hit O'Brien with was awesome and so was that one punch knockout Johnson pulled off.
The Sherdog stream was pretty crappy (Like they usually are). The sound was cutting in and out a lot but once the main card started things were good.
It was a little strange to see Michael Schiavello call the prelims and then vanish for the main card. Bas had a good showing as always though

I'm very interested in their 2nd show. I expect a few key improvements. They already have a great fight in the bag (Tyson Nam vs. Marlon Moraes). I wonder if they'll get Arlovski and Johnson to fight again as well since neither guy really took any damage.
Overall I'd say their first show was a success. If I had to give it a letter grade it would be a B.
Sefo is a good guy who has a passion for combat sports. I can't wait to see if this works out for him.
