I'm guessing that Silva will work a lot on his takedown defense and keep the fight standing. Once that is accomplished it will all be downhill from there. I wouldn't be surprised if this fight ends fast either. I don't want it to end early for entertainment purposes but a couple of well-times strikes (knees, punches, kicks) is all he will need to put chael to sleep.
I haven't been excited about a fight like this since hatton fought mayweather.
