Golf Channel analyst Brandel Chamblee is a bit like Skip Bayless. Bold, smart, and never wary of sharing his often bold opinions.

Being that Rory McIlroy is among the very best golfers in the world, he’s a frequent topic of discussion for Chamblee. The two bumped heads last year when Chamblee criticized Rory’s workout habits, and now, their Twitter feud is flaring up again.

It started when Chamblee claimed that the best drivers of the golf ball actually hit “down” on the ball, rather than “up” on it. That may sound stupid and wonky to non golf nerds (because it is), but it’s actually a pretty contentious take in the golf community. Then, he tried to prove his point by sharing this picture of Jack Nicklaus.

Enter Rory.

@chambleebrandel @flightscopePhD It's 2017 and Jordan is hitting a 3 wood in that photo. To get the most out of modern equipment you need to hit up on the driver. #fact pic.twitter.com/sBGGMN9lBn — Rory McIlroy (@McIlroyRory) January 18, 2017

(That’s 356 yards in the picture above, by the way)

But wait, it gets better. The killer blow was brutal, and utterly brilliant.

Pretty sure hitting up with your driver works @chambleebrandel 😉 pic.twitter.com/OLU3ZO815C — Rory McIlroy (@McIlroyRory) January 18, 2017

And now, let’s go live to Rory McIlroy.
