Brock has fought once in 7 years...Brock gases very quickly...Brock takes him down before he tires (usually in the first few minutes) he wins win ease. I don't care what the oddsmakers set the line at. I very seldom ever lose a boxing/mma wager. For me, I can't stand the guy for many of reasons and I will bet heavy against him if he comes back. If I lose, I will just make it back on another. Jones is a true HW and for the countless number of times, why doesn't he fight HW. It will be so easy for Jones in HW as you say, he wants no part of the big guys for many of reasons. The Brock fight is more of a circus act than anything. Gus made Jones face look like hamburger, imagine what these guys would do. Gus was the only guy he fought with the same reach, height, and strength and that fight was a draw or win for Gus in my eyes. Put him against the following. Jones lacks speed, power, and strength against these guys
Derrick Lewis
Mark Hunt
Alistair Overeem
Curtis Blaydes
Francis Ngannou
Andrei Arlovski
Stipe Miocic
If you think Brock Lesnar would beat Jon Jones with ease, you are watching a different sport than I am.
