Jalen Duren: From Young Defender to Defensive Anchor
Jalen Duren has made one of the most eye‑opening leaps in the league this season, transforming a previously “glaring weakness” into a true defensive strength. Once targeted by teams pulling him away from the rim, Duren’s improved footwork, anticipation, and on‑ball coverage have elevated the Pistons’ interior defense and erased a major vulnerability from their game. This season’s progress is so noticeable that analysts have included him atop The Athletic’s list of players who’ve surprised the most with how much they’ve grown across multiple facets of play.
Nickeil Alexander‑Walker: Rising Scoring Force in Atlanta
Nickeil Alexander‑Walker has defied expectations in his first season with the Atlanta Hawks, stepping up as a key offensive contributor. After signing a significant multi‑year deal in 2025, Alexander‑Walker has thrived within Atlanta’s system, averaging career‑high scoring figures and emerging as one of the core pieces in their recent surge up the Eastern Conference standings. Hawks statistical breakdowns show him averaging over 20 points per game in recent weeks, establishing himself not just as a role scorer but a primary offensive option during crucial stretches.
Jaylon Tyson: Second‑Year Breakout Star for Cavaliers
Jaylon Tyson has taken a significant leap in just his second NBA season, turning a modest rookie campaign into a breakout year that’s earned him national attention. Now a regular starter for the Cleveland Cavaliers, Tyson was selected to the NBA’s Rising Stars Game in 2026—a testament to his increased scoring, improved three‑point shooting, and all‑around impact. Backed by mentorship from veteran Donovan Mitchell, he’s averaging career highs in points, rebounds, and assists, and has become a legitimate candidate in discussions around Most Improved Player nods.
Ajay Mitchell: Emerging Thunder Spark Plug
Ajay Mitchell has quietly morphed into a high‑impact role player for the Oklahoma City Thunder. Despite being a second‑round pick, Mitchell’s offensive efficiency and defensive contributions have made him one of the more intriguing young bench scorers in the league. Some early season award projections even pegged him as a dark horse candidate for Sixth Man of the Year, highlighting his well‑rounded game and ability to influence the scoreboard in multiple ways.
The All‑Surprise Team: Honoring Unforeseen Breakouts
This season’s All‑Surprise Team celebrates the players who’ve made the most dramatic and unexpected improvements—stretching beyond raw talent to real, on‑court influence. From established young stars like Duren anchoring team defenses, to breakout scorers like Alexander‑Walker and versatile newcomers such as Tyson and Mitchell reshaping their roles, this group has made waves far beyond preseason projections. Their ascents reflect not only individual skill growth but also how quickly impact can shift narratives in a league as competitive as the NBA.
