Corner McGregor and Mayweather prediction

As everyone of us were eagerly waiting for this day wherein Mayweather will have his streak of 49-0 on hold as he faces Corner McGregor today
Floyd Joy Mayweather Jr. (born Floyd Joy Sinclair; February 24, 1977) is an American professional boxer and promoter. Mayweather is undefeated in his professional boxing career and a five-division world champion, having won fifteen world titles and the lineal championship in four different weight classes (twice at welterweight).[1] As an amateur he won a bronze medal in the featherweight division at the 1996 Olympics, three U.S. Golden Gloves championships (at light flyweight, flyweight, and featherweight), and the U.S. national championship at featherweight.

Conor Anthony McGregor (Irish: Conchúr Antóin Mac Gréagóir; born 14 July 1988) is an Irish professional mixed martial artist and professional boxer who is currently signed to the Ultimate Fighting Championship (UFC). He is the reigning UFC Lightweight Champion, and former UFC Featherweight Champion. During his mixed martial arts (MMA) career, McGregor has competed as a featherweight, lightweight, and welterweight.
According to me as per the previous matches is to be considered Mayweather holds an edge over Corner McGregor but we cannot consider McGregor out of the contest as he was both lightweight and featherweight champion at a time
