No need to be rude. If we can't offer our thoughts on a forum dedicated to MMA what is the point?
I don't really care much about alex. He is pretty clearly a journeyman at this point.
But Yair obviously isn't hitting that hard with his strikes, and this is a problem for a prospect. It isn't so much a matter of KO power, but if doesn't have the ability to make the top 10 fighters respect his strikes, they will walk straight through him.
You don't need to be a genius to know that there is a problem when someone connects with a dozen head kicks and the other fighter stays standing there might be some cause for concern.
Also, I ain't saying anything that several pro fighters have already said publicly.
