MMA is the only sport you can walk into with big athletic ability and reach the top within 2-3 years
Look at Greg Hardy, athletic as hell and a former NFL Pro Bowler, MMA debut in 2018 and by 2020 he is on UFC's main card
Greg Hardy could never make it that high in that short amount of time in any other major sport, no way he makes the NBA or MLB within 5 years if ever
No way he moves up that fast in boxing either, it takes years to reach top level status
So what does Greg Hardy say about MMA being a legit top tier sport?
