I'd like to give both cooper and kincaid the benefit of the doubt regarding injury.
I do not have elite athletic skills, but I used to be a decent golfer. I was certainly not as long as a pro, and I wasn't scratch. But I could hit it pretty good. I had lower back surgery (removed my tailbone and 1/2 of my sacrum, moved my glute muscles around to deal with that) and looking at me, you'd never know. I'm essentially the same guy. Nobody can tell. But I can. I have the same swing, but I've lost 30 yards of distance off the tee, and it isn't just age. My rounds under 80 are not common now. Occasional, not regular.
My point is that people have no idea what an injury can do to an athlete. My swing changes are minor to the untrained eye. Imagine an elite athlete dealing with an injury that impacts their training and what they do. Your brain thinks your body can do what it used to, but somehow your body just doesn't respond. Fans like us can't see the difference. But players can feel it and it is a real thing.
I expect Kincaid to bounce back after he fully heals. Cooper isn't the same story. He's older, and just won't bounce back. Don't underestimate the impact of a lower body injury on an elite athlete. Kincaid will be fine.
