His swing is looking real good. Looks like his putter is too long for him though, he's gripping way down on that thing.
I like what he's doing and I think he's going about learning the game the right way. I read Outliers and the 10,000 hour theory is an interesting one. I calculated once that if I quit my job and practiced 3 hours a day I'd be ready for the senior tour! Only thing holding him back is that I think there's a lot to be said for grooving muscle memory when you're young as opposed to in your twenties.
