Caddies aren’t just donkeys that hold bags for truly great golfers. True, while the best caddie in the world isn’t going to make me a competitor for the PGA tour (I don’t think I can even name more than two golf clubs if I’m being honest), ABC News did an interesting piece that featured thoughts from pro-golfers on what makes a great caddie.

One unnamed champ said, “Trust, knowledge, and maturity. And thick f–king skin.”

And if the stories about Bryson DeChambeau are to be believed, then Tim Tucker must’ve had a very thick skin to work with the champ. But it doesn’t seem like it was enough to keep the pair together for the Rocket Mortgage Classic Bryson’s set to compete in.

That’s because The Big Lead has reported Bryson and Tim will no longer be working with one another. Instead, Ben Schomin will be replacing him in a move that surprised many, as Tim was seen at Bryson’s side during the practice rounds leading up to the big tournament.

Like any good breakup story, everyone wants to know who dumped whom, and in this instance, No Laying Up reported that it was actually Tim Tucker’s decision for him and DeChambeau to go their separate ways. Bryson has been known to complain about seemingly minuscule and/or ridiculous “obstacles” on the green. One time, he tried to get a ball drop because of ants.

Whatever transpired between the two men, it must have been a huge deal, considering the fact that the two have had a lot of success with one another over the years. Caddies typically make anywhere from five to 10 perfect of the tournament winnings on top of their salaries. This means that Tim is foregoing a potentially huge payday, especially since he and Bryson took home the top prize last year.

The Rocket Mortgage Classic’s top winner will bring home $1,350,000, on top of sponsorship money and other funds. This means that Tim is giving up anywhere from $67,500 to $135,000 if Bryson wins, not to mention that second and third place prize money isn’t exactly chopped liver either.
