Sorry, but I don't think this has anything to do with the gi. Two guys decided to play footsies for 10 minutes. I've seen it in the gi at both high and low levels, and I have seen it in nogi as well. Compare the Vinny v Buchecha video above to Rodolfo v Buchecha last week, and it will seem like gi is WAY more exciting. It's not, though, it's just that some matches are great, some suck.
If you find gi fights boring, target specific fighters who are consistently active. Watch Rafa Mendes, Ryan Hall, Marcelo, etc.
