When Cub has lost a fight he always questions himself, his team and everything in regards to improvement and bettering his game, this isn't anything to do with not being loyal it's to do with wanting to improve in your profession and be the best while you can in the profession which as we know isn't always long term.
It's not exclusive to Cub either, how many times do people say about looking at a fighters camp and how they need to change this, I've heard it a lot in regards to Cody Garbrandt and recently I've heard it a little in regards to Al Iaquinta.
Also when fighters change camps it's never personal and many times they remain friends and remain loyal that way also, if I was a trainer and knew I wasn't benefiting my fighter I would want to let them go to improve and be better to someone who can give them a better camp than I could, it's not personal and we'd also be loyal within friendship with gratitude and appreciation (in fact it might be a better friendship without business involved).
Imagine if this was the case for every fighter, none would progress and imagine how it would be if they were all like "We can't leave this camp now", even if we know the camp isn't really doing them any favours or bringing out their potential.
It's also a living and a career too, they need to be the best to earn the money for their family or themselves to live in general which is another reason why it wouldn't be personal and I would let the fighter go if I wasn't bringing them that full potential.
Also, Kron is talking from a family lineage too, completely different.
