Hardy is the one coach that actually gave Lauri the responsibility as the # 1 option. Yes the jazz mainly traded for the picks but after seeing him play that summer they believed in and trusted him to be the man. Lauri owes a lot to the Jazz and Hardy for turning his career around.
His first two seasons Lauri obviously wasn't ready to be a star player and the Bulls already had LaVine as the #1 guy. Then Jim Boylen tried to make him bulk up and be a traditional 5. Which was immensely stupid. Not doing that is nothing to get plaudits for. As far as unlocking much of his current playing style already happened with the Cavs by Bickerstaff even if that didn't show up in the box score. But all the movement, cutting, playing 3 and taking advantage of Lauri's talent happened in Cleveland.
And as far as the "responsibility of #1 option". JC took more shots last year until the final tanking phase. JC always had the ball in his hands end of quarter, end of game. Hardy didn't and doesn't run that many plays for Lauri.
Hardy's system would've been the same, Lauri or no Lauri. It just happened that a high movement offense that has tons of options, options off of options and options off of... brings out the best in Lauri.
So what exactly did Hardy do? Declare publicly that Lauri is the best player on the team after he had proven that he's the best player on the team. Well, d'uh.
And of course Hardy and the whole staff has helped him develop a lot, they've tried to build up his confidence, bring him out of his shell etc. But that's what you would expect any coach to do if they have a player like Lauri on their roster.
Ya'll can mock me for this because I have zero data-driven evidence, but my general feeling is that European players don't like to move. Roots and community are important to them. Jokic will be in Denver his entire career. Rudy would have stayed if he wasn't dealt. Parker and the Spurs. Earlier in the year, Lauri was pleading with Ainge in the press not to trade him because he likes Salt Lake and what they're building.
I dunno - you all think this is a thing or am I off my rocker here?
The cultural differences are just massive. Keyonte talked about "gonna build my brand" when he talked about the Rising Stars game, which is just so different from any European players thought process. There's a concept of "generational wealth", which translates to getting hundreds of millions as a measurement of your success. Again, something completely alien to Europeans. The fame, the brand, the face on the side of a building etc.
There are more flamboyant euros as well, but most are thinking much more humbly. Jokic cares about his horses and cycles to the stables, doesn't show up in a Lambo and a flashy suit. Lauri's most expensive hobby is disc golf, and you're gonna struggle to spend more than a few hundred bucks for discs and a god bag.
And even if the player is a social butterfly and could go into a new team easily, the situation is a lot different for the family. If their wife is also not American, they're in an unfamiliar environment, speaking another language - same goes for the kids, at least for the language. Getting past that unfamiliarity and your normal life functioning is harder, and once you've done it, you want to keep things as they are. Also, the support network might not be available. If an American player gets traded, just call up family and friends to help with everything - not so easy for Europeans.
