So let's take a look at the French, and now German PG, Killian Hayes. Hayes was born in Lakeland Florida, but grew up in Europe, and mostly France, where he started to make a name for himself on the French National Team by winning the MVP award on their FIBA U16 team. He accomplished this by averaging 16.6 ppg, 7 rpg, and 5.1 apg, and leading them to the gold medal. That same year he was invited to the Jordan Brand Classic where he won the co-MVP award.
His father was a star at Penn St. who today would have likely ended up playing in the NBA, but back then he got lost in the shuffle and ended up playing in the European league. Killian's dream was to play his highschool ball in the United States, and then win an All American award by attending a school like Kentucky or Duke. However, his father had different ideas, which included getting his feet wet in the professional European league, thinking it would toughen him up and prepare him better for the NBA.
Killian is a 6'5" PG who can also play SG. He has excellent court vision, and is a very good passer. He has very good handles and a freezing crossover. This season he switched from the French team to a German team where he's averaging 26.8 mpg (a lot for such a young player in the European league), 12.2 ppg, while shooting 45.5% overall, and 39.0% from the three. He's also averaging 90.9% from the free throw line, 6.2 assists and 1.5 steals. That's through his first 10 games.
He's good at pushing the ball up the court, and attacking the basket, where he makes things happen. He's also very good at running the P&R, either in the lane, or from the side. He's a pretty good passer in traffic, at times dazzling you with a pass that almost seems magical. Did I mention that he's a lefty, (you can't have too many left handed players on your team) and that when attacking the basket, he definitely leans hard toward his left hand. That's not to say he can't finish with his right, but doesn't seem nearly as comfortable when doing so.
So far I've liked what I've seen from him defensively. He battles through picks and has good pursuit when beaten off the dribble. In general it takes a pick to free up who he's guarding. He has very good lateral quickness and good instincts, but at times seems to lose focus, or perhaps ball watches a bit too much. He also gambles in the passing lanes a bit too much. But most of his flaws are correctable. It will be interesting to see what his real weight is. I've seen it listed from 178 pounds all the way up to 218 pounds, and many in between. But whatever it is, he isn't afraid of contact.
Here's a video. By the way, the player he says he patterns his game after is James Harden, so his 35 foot jumper is going to need some improvement.
