After watching the Davis Cup match against Ito, I have several things to say:
He has nearly 0 talent. Sad, but true. The shotmaking ability isnt that good, not enough consistency to be a good player, doesnt have a good backhand. Ito however, is atrocious.
The good thing which can be said about Amir is that he has a deceptively excellent serve. He does place it quite well all over the box, I would actually say that his serve might be in the top 10 current serves on the ATP tour. He has a much better serve than most top 100 players.
Still, good win for him!
The only assessment I trust in your post is the one about Ito.
Weintraub a top 10 serve? Lol...And what's wrong with his backhand?
