As a five-star high school recruit in 2022, Walsh committed to Arkansas, joining future first round pick freshmen Anthony Black and Nick Smith. He had a pretty modest freshman season from a production standpoint, but he showed real flashes of being a potential good NBA role player, and performed well enough at the combine to get selected 38th overall by the Celtics. Walsh has a good frame at 6'6" with a near 7'2" wingspan. He has good lateral quickness and strength, so it's likely he'll be able to defend multiple positions in the NBA. He has pretty good explosiveness too, so he has real NBA athleticism overall.  Offensively, Walsh plays hard and should be a good transition threat. He needs to improve from a shooting perspective to be a real offensive threat, and needs to improve his ball-handling and passing to be a threat with the ball in his hands. His 35% 3-point shooting on 240 total attempts in the G-League is a good sign though, even though he hasn't shot well in the NBA on a limited sample size. Walsh will still only be 21 years old as a potential free agent in 2025. As a fairly high 2nd round pick and someone that the Celtics seem very intrigued with, I would be surprised if he actually hit free agency in 2025. In '24-'25, Walsh got more NBA minutes after not really playing at all as a rookie, but he was still not in the regular rotation and didn't get any playoff minutes. He finished well at the rim but didn't get there often, and struggled to hit jump shots.
