Ortiz. He has the size and explosiveness with his hand/foot speed to burst forward and catch Khan. It would be competitive, since Khan has good movement and has his way on the outside, but Ortiz I think would eventually close the distance and hurt him with a good shot. Khan isn't calm enough under fire and Ortiz's brand of aggression would penetrate Khan's guard before long.
i give the slight edge to khan if they were to fight. he has more to his game than ortiz has. but, this would be a great fight that could go any way. i wouldn't really rule anything out. forget about khan beating ortiz easily in the AM's, that doesn't matter. in the pro's it's a tough fight for both. let's hope it happens down the line to find out.
They both have Glass Jaws but Khan has no power and can't handle pressure. Ortiz would brutally KO him, and early.
