Who used/uses the high guard effectively?

[Illmatic94]

Winky the best at it.. But Jermain Taylor was penetrating him with power shots all night, left his forehead all lumpy and bruised. So it helps to have a good beard to use this stance because some wicked sht is bound to get through.

Is Broner going to apply the high guard again all night like in the Mickey fight or what?
If he is, then Vargas wins, possibly by KO.
