Allonzo Trier Scouting Report


  • Allonzo Trier was the 18th-ranked prospect in the 2015 high school class[1].
  • In three seasons at Arizona, the six-foot-five wing accumulated 2,456 minutes of college basketball experience.
    • Other than that, he has 139 minutes at the 2013 and 2014 Nike Global Challenge and 182 minutes defending the United States National Team at the 2014 U18 FIBA Americas and 2015 U19 FIBA World Cup[2].
  • Most recently, he averaged 21.3 points per 40 minutes[3] on 65.6% true shooting and compiled a 21.1 PER in 33 appearances last season.
  • Arizona played only the 68th-toughest schedule in the country[4] and had a +22.7 pace-adjusted point differential in Trier’s 1,124 minutes[5].
  • The 22-year-old[6] had a lot of shot creation responsibility against a set defense, not just running point when Parker Jackson-Cartwright subbed out but as the most capable dribble penetrator on the team even with the diminutive lead guard in the game.
    • Trier logged 23.8% usage rate and assisted on 17.3% of Arizona’s scores when he was on the floor last season.
    • He was assisted on just 36.4% of his 184 field-goals[7].
    • His 129 offensive rating was far better than the team’s overall 114.7.
  • On the other end, the Findlay Prep product put in decent effort in individual defense and proved he is able to execute the scheme but doesn’t have enough athleticism to make a real positive contribution and isn’t instinctive enough to create events in volume.
    • He had the third worst defensive rating on the team among rotation players and Arizona defended better without him on the floor.


  • The Seattle native doesn’t have an explosive first step and isn’t very fast with the ball. He is also not very shifty side-to-side. But he has proven to be very resourceful off the dribble, getting by his man or creating separation on craft.
  • He has an in-and-out dribble, hesitation moves and an euro-step to get his man off balance and maneuver his way through traffic. When he ran point and was guarded by smaller players, Trier also relied on his well-distributed 205-pound frame[8] to maintain his balance through contact.
  • He flashed some explosive leaping ability off one foot sprinting up the court to fill the lane in transition but isn’t able to go up strong in the half-court often, acting mostly as a rim level finisher. A good one at that, though. Trier has shown to be an ambidextrous finisher and able to adjust his body in the air for acrobatic finishes around rim protectors.
    • Trier finished his 99 shots at the rim at a 75.8% clip.
    • He didn’t put a ton of pressure at the rim last season, taking just 26.9% of his shots within close range and earning 6.6 foul shots per 40 minutes, due to Arizona’s poor spacing. The year before, with Lauri Markkanen opening the lane, Trier took 30.8% of his shots at the basket and averaged 8.1 free throws per 40 minutes.
  • Operating in middle high pick-and-roll:
    • He flashed a hesitation move to get into the lane but for the most part showed a strong preference for setting up step-back and side-step pull-ups, not just from the elbow area but also proving he’s able to make jumpers off the dribble from long range;
      • 40% of his three-point makes were unassisted.
      • Trier shot 45.9% on 85 shots from mid-range, with just one of his 39 makes from this zone assisted.
    • He doesn’t have advanced court vision in terms of tying up the help defense and tossing up lobs in traffic or making passes across his body to the opposite end of the floor but showed improvement year over year and is now a decent simple passer off the ball screen, able to deliver the pass over the top to the roll man and the skip pass in the pick-and-pop;
      • His assist rate went from 7.7% in year one through 16.2% in year two to 17.3% in year three.
    • He keeps his dribble alive against blitzes and looks to protect the ball in traffic.
      • His average of 2.5 turnovers per 40 minutes is not great but not that crippling for someone who was tasked with creating on the ball as much as he was.
    • Trier doesn’t offer a lot of versatility as a shooter, other than the eventual one-dribble elbow pull-up off a dribble hand-off. But he has evolved into a very solid spot-up gunner.
      • Trier gets little elevation, has a pronounced dip for rhythm and releases out in front but managed to get good arc on his shot and launch over closeouts comfortably in college. He still has room to work on the speed and fluidity of his release to be as effective in the pros, though.
      • Trier nailed 38% of his 184 three-point shots last season, at a pace of 6.5 such attempts per 40 minutes. He hit 37.8% of his 381 three-point attempts and 82.7% of his 446 free throws over his time at Arizona.


  • Trier bends his knees to get down in a stance in one-on-one defense and can shuffle his feet laterally for two or three slides to stay in front for the initial push. But he doesn’t use his strength to contain dribble penetration through contact and eventually gets beaten if help isn’t shadowing the isolation close by.
  • Off ball, Trier can be caught ball watching from time-to-time, isn’t agile enough to chase shooters off screens and his closeouts are either weak or he flies by and exposes the defense behind him. He has a below average six-foot-six wingspan[9], lacking great length to make plays in the passing lanes often.
    • He averaged just 0.7 steals per 40 minutes last season.
  • Trier executes the scheme as a weak-side defender, stunting inside to clog driving lanes and rotating in to help crowd the area near the basket. He doesn’t have explosive leaping ability or the length to aid the rim protection effort.
  • Trier doesn’t offer versatility picking up different types of players on switches:
    • He is unable to get skinny navigating over screens at the point of attack and lacks agility to hustle back to his man in an attempt to bother or actively challenge the ball handler from behind;
    • He is not bulky, lengthy or tenacious enough to guard bigger players in the post or box them out.
  • His contribution on the defensive glass was below average.
    • He collected just 9% of opponents’ misses when he was on the floor last season and that rate was 11.8% over his three seasons in Tucson.
