Well if you're trying to judge the guy by one fight, then that would be a big mistake. There's no doubt Silva's skills are impressive.
The matchup wasn't great, we agree on that, but that's Dana's responsibility.
If you're new to the sport then I understand how you can feel that way, but I saw nothing that hinted at Silva being scared. This isn't football where you make a mistake, there's another possession or another down.
You might not have gotten to see his best work, but considering he left the guy bloodied, bruised and humiliated, I think you got to see him fight especially when the other guy was doing everything in his power to avoid fighting.
If you didn't see the art in his knee strikes, his feints, avoiding the takedowns, amazing defense on the ground, his explosiveness, etc in that fight, then I don't know that you were paying attention.
It wasn't a slug fest, and everyone loves a good slugfest, but as far as technique, Anderson was impeccable, as always.
