Maybe he really was great and then something happened that changed him
As an example, my bro has hit a rough patch the last few years. He poured his heart and soul into a business for 10 years, and it ultimately turned out to be a bust. That has really taken a toll on him. He is still awesome in many ways, but he is kind of a shell of his former self right now. I think he can get back to being his old happy self again, but he’s going to need a lot of support and he’s going to need to be willing do some brave stuff to get himself back in the ring again. Life is tough.
