It's difficult to get full game video on players instead of just watching highlights. I couldn't find any Euro League games on Avdija, but I did find the 2019 FIBA U20 European Championship. The Wiki page links to the FIBA page where you can get complete boxscores and watch full game replays. I killed nearly six hours watching Avdija in the quarter, semi, and final games. It was some really good basketball and fun to watch how hard those national teams compete. The style is pretty hard-nose, basically like watching Big Ten basketball. But the stakes were much higher, and you could tell the teams were highly vested. These three games from a year ago were stiffer competition than the three games Wiseman played in college. Then he went on to play another season in the Euro League.
Overall, Avdija was really fun to watch and impacts the game in nearly all areas - even if his shooting is off. He was the second youngest player in the tournament, but won the MVP award averaging 18.4 points, 8.3 rebounds, 5.3 assists, 2.4 blocks and 2.1 steals per game. He was more athletic than I was anticipating. Very good straight-line speed. Decent leaper off one or two feet. Has a little glide/hang on his takes (needs to finish more consistently). Light on his feet for the second jump. Contests/blocks shots without fouling. The team's defensive scheme was to switch nearly everything, so you literally can watch him guard 1-5. France has a really small point guard and a thick post, and Deni does well against either. His BBIQ is off the charts. He understands spacing and pacing. His turnovers were usually poor execution and not poor recognition. He already has very good handles and shooting stroke - arguably was the team's primary ball handler. Probably most importantly, he's an alpha dog that competes hard and did not shrink in big moments of really big games. You can see he hates failure.
Quarterfinals against Lithuania
16 points, 10 boards, 5 assists, 3 steals, 4 blocks, 3/8 FT, 1/5 3PT
Semifinal against France
26 points, 11 boards, 1 assist, 5 steals, 3 blocks, 12/14 FT, 2/5 3PT
Finals against Spain
23 points, 5 boards, 7 assists, 1 steal, 3 blocks, 2/3 FT, 3/7 3PT.
This is a decent look at Deni that goes back to his early years and shows his development as a pro. You can see his body change and you get a better idea that he has actually been a pro - not a college player - for years. Likely better for development than AAU over the same period. I'm not buying the Luka comp as much as this guy is pushing, but I do agree he will be a very good play maker in the NBA. His player profile page for the Euro League actually lists him as a guard. Having watched the three full game videos I would list him a positionless basketball player. He is Ben Simmons with a better jump shot.
