Over the past months, since I started getting back into "shape", I've had a number of people jokingly ask if I was preparing for my MMA debut.  This got me to thinking, Do you think you could be competitive in a MMA fight.  Some people have what it takes; while others do not.  Some people look the part; while others do not.

Prime example: 
                                                    


If you ran into "Big Country" Roy Nelson on the streets, would you think he was a top-tier MMA fighter, and Jiu-Jitsu Blackbelt?  But he can take a punch better than most anyone in the sport and keep on ticking. 

How about this guy:
                                                        

We saw him get BEATEN for 22 minutes and then submit a fighter from his back.  Sherdog has him listed as Number 2 Pound for Pound best fighter in the world.

I'm not asking if you think you can hang in there with a fight against these athletes,  but what driving forces would help you be a MMA fighter?
