Yes, ground stomps and soccer kicks would be good for entertainment.
Would give more weapons to stand-up fighters.
Anyway, i don't think it was fixed, both sides had opportunities to win by ko, it came close a couple of times. But i must admit that i was disappointed a bit in Silva. I think the fight against Mirco changed something in his head. If you watch that again, crocop really destroyed him. Losing like that can break your confidence, which is very important in a fight.
But i understand why he fought a bit conservative. Chuck is a dangerous striker and he has height+reach advantage. He'd love for a guy to come in swinging haymakers, just to put him down with one counterpunch.
