He might never get to "elite" status as a disc golfer, but I would expect him to improve rapidly.
We tell everybody that to improve, you need to learn how to throw putters and understable discs. Well, this guy has been mastering slow, understable discs for 15 years. He knows how wind affects flights. He knows release angles. Ultimate and disc golf aren't the same, but the physics are consistent.
We tell everyone that if you want to improve, study people that are better you. Brody is currently practicing his distance drives, with Emerson Keith holding the rangefinder. Later this month he's gonna spend a week getting tutored by Simon Lizotte and Paul McBeth.
And most of all, anyone who wants to improve is going to need time and practice. By starting out with a sponsorship and no "day job", he's going to have more time and money to invest in disc golf than almost anyone. I don't know the terms of his Discraft deal is, but I'd wager that it's one of the biggest deals in the sport.
Brodie's growth as golfer is not going to follow a typical growth pattern because Brodie's situation is not at all typical.
