The crazy part is I'm 100% convinced that Tyron would fight like this regardless of who you put him in there with right now. Literally, like even some no-name dude off the indies. Whatever is going on is between his ears.
It's like if a Major League Baseball player put some years in, won a World Series or a Golden Glove or two, then out of nowhere he comes back for the season and is scared of the ball. Covering his face, whiffing, making all kinds of errors and shyt, and playing like he's scared. Camera cuts to him several times in the game and he's a deer in the headlights.
I don't know of a strategy or sparring partner that can fix that. Bruh either has a psychological block or just flat out doesn't have this fight shyt in him anymore.
