First of all, I just watched it for the first time. That was an incredibly boring match. Note, this is in no way to insult either wrestler. They both had a game plan, and I am in no position to question that. However, it was simply a boring match. Anyone that says otherwise is most likely bias.
Secondly, I would have called both wrestlers for stalling in the first period. I have no problem with the stalling call in the second period to give Korb a point. At that time, he was the only wrestler to really attempt to score. It did look bad, because at almost the exact time the ref decided to hit Gresham for stalling, Gresham reshot and was in his best position the entire match to score a takedown. Gresham finally opened up and was more aggressive in his attempt to score after the second stalling call.
Third, both wrestlers need some serious work on their riding skills if they want to succeed on the next level.
Lastly, IMO, Korb outwrestled Gresham in this particular match and deserved to win. I also think Korb is a better wrestler, but that is no knock really on Gresham. Gresham is very quick and explosive in his own right.
