Seriously though here is what I think of villa. He made his senior debut for Barcelona as a 16 year old. That is on of the best non nba teams on the planet and most of their guys are highly paid professionals. The gasol brothers came through the Barcelona system (although Marc also played high school ball in Memphis) as did Ricky Rubio. Villa has been in the Barcelona system since he was 12 and was the youngest Barcelona prospect to ever make a senior team debut. At that point he was also playing with the Spain u 18 team as a 16 year old so that is big time
Last year as best I can tell he had a disappointing season based both on the limited stats we have and the fact that he apparently didn't get another call up to the Barcelona senior team. Also his star must have faded a bit for us to even be having the conversation. Barcelona has trained him since he was 12 and although they apparently did offer him a professional contract, it must not be too big if he is willing to walk away from Barcelona and play college Basketball.
So I have no idea how good he is. But I am sure he is better than Peyton Allen. Worst case he is the same player but 6 inches taller.
