It is pretty obvious that Rashad wanted to use the jab to set up the takedowns, and he did clinch with Jones a few times but didn't have the strength to take him down. This doomed him. With Jones' reach and athleticism, a stand-up war garanteed him the win.
Rashad's speed and power did allow him to hurt Jones. He lended a good kick to Jones's temple in the first round, and then a right overhand in the second round. But Jones' reach, athleticism and versatility and those elbows assured him the win.
I am not impressed with Jon Jones. He is very good, but not this super-dominant force people make him out to be. He is 6'5 with shoulders as wide as an oarsman and an 84" reach, and yet he couldn't finish a 5'11 man with a 76" reach.
Based on what I saw, he would get devoured at the HW division by guys like JDS, Overeem and Cain Velasquez
