They spent much of that match in 50/50.
As much as Buchecha may be better in the gi than nogi. I think this is more-so a case of Vinny being outstanding at nogi. That is where Vinny can excel to insane levels - not so much in the gi - but nogi, he can beat anyone in the world. I believe Buchecha has improved since that fight; however, and it would be awesome to see them go at it nogi again.
