I won't disagree with what you said, I would have said exactly the same things you said several seasons ago however the game has changed due to buzzerbeater changing and managers adapting to these changes. The players you need in the yesteryear especially at division 1 and national level are totally different. If you are aiming to win championships and cups, you need some sort of edge. Something that puts you at a level above others that makes you difficult and unlikely to beat. Whether it's for personal benefit: league, cup, B3 or even for the national team's benefit there will be someone who is willing to train him up because he could be trained to become only 1 of maybe 20 players in all of buzzerbeater. That's why teams will buy him and train him to become a unique player. That's why you see countries buy rival country's players and try to fire them or get them out of gameshape. People go to great lengths just get an edge over others.
By the way, what's with all these non-ABBL trolls ;)
