A successful MMA career could last an extremely long time. Take Jim Miller, for example, who made his UFC debut in 2008. Or look at the career of Clay Guida, a man who debuted back in 2006. We watch them grow in the sport, both in a professional sense and physically.
Raul Rosas Jr gained a UFC contract at 17, meaning he could have upwards of 20 years in the sport. To look at him on his debut in comparison to 20 years time will show a stark difference.
We take a look at UFC fighters who look considerably different now, in comparison to when they made their UFC debut.
