The size difference is too big. Let's assume they are equal strength, with that much leverage from jones and gravity working against Cormier, it's a recipe for disaster but he kept doing it til the end. I can't speculate what the right game plan would have been . I mean obviously it's to take the taller guys legs out but DC proved he couldn't do that either. And then theres the striking where he got brutally outranged. Really not sure what DC could have done different to have a more effective fight, over all he done ok, fought pretty gutsy but Jones is just a much better fighter, younger and genetically has an advantage thats very hard to overcome.
