This thread being bumped was a bit bittersweet. Miss PhoSita & rollie, but their contributions were always fun.
Not really hopeful of anything from Yam. Begarin, maybe? Not sure - seems unlikely.
I think you're too down on Madar. Winning the Rising Star award in Europe is not a small deal. Here are the past winners:
2005 - Erazem Lorbek
2006 - Andrea Bargnani
2007 - Rudy Fernandez
2008 - Danilo Gallinari
2009 - Novica Velickovic
2010 - Ricky Rubio
2011 - Nikola Mirotic
2012 - Nikola Mirotic
2013 - Kostas Papanikolaou
2014 - Bogdan Bogdanovic
2015 - Bogdan Bogdanovic
2016 - Alex Abrines
2017 - Luka Doncic
2018 - Luka Doncic
2019 - Goga Bitadze
2021 - Usman Garuba
2022 - Rokas Jokubaitis
The majority of that list became NBA rotation players at some point in their career.
He was also only the fourth player to win the award in his first Euroleague season, with Fernandez, Gallo, and Jokubaitis the other three.
I'm not predicting stardom for Madar, but I do think if he were in the draft this year he'd be a second-round pick again. I don't think his future is in Boston, however.
