The problem

He won't become a pro player again, because he has way way way too many other projects going on. He's discussed the reasons why he won't do it, more in depth in a daily before, I just can't remember which one it was. Possibly one of his Q&As? Anyway, he would have a give up a lot to be able to maintain the practice schedule he needs to stay competitive. And that doesn't count all the time he would need to put into improving his play or coming up with new ideas. I'd be surprised if he could be a pro player and keep doing the daily.
