Without a doubt, KU’s biggest off-season win was the announced return of Jalen Wilson. The incoming redshirt junior has started 53 games in his career, the bulk of his two full seasons as a healthy Jayhawk. But how good can he be this season? Let’s try and find out.
Let’s first look at Jalen’s per game stats since coming to Lawrence.

After being injured for nearly the entire 2020 season, Wilson emerged as KU’s best scorer to begin his redshirt freshman campaign in the 2021 season. He averaged 15.1 PPG over his first 10 games that year. And while he cooled off some, he finished 2021 as KU’s third-leading scorer and leading rebounder. Coming into 2022, Wilson was expected to pick up where he left off. But after poor off-court choices and a suspension to start the season, Wilson started slow, only reaching double-figures in scoring in his 7th game of the season (team’s 10th game). But he picked it up, finishing the season with double-figure scoring games in 22 of his 37 games played. In the NCAA Tourney, he posted double-figures in 5 of the 6 games.
Where Wilson has shown strength is in isolation offense. A great example came against Providence in the Sweet 16. When KU needed a basket after giving up the lead, they went to Wilson. See 1:06:40 of this video: https://www.youtube.com/watch?v=oZ4dOprMnHI&t=2746s
Wilson got a good matchup and exploited it, but this has been his m.o. while at Kansas. This play is memorable because it came at a big moment, but Wilson has had this ability since he got to Kansas.
One area Wilson improved was on-ball defense. A few minutes after his and-1, he made this play against a Providence guard. See 1:08:53 in video: https://www.youtube.com/watch?v=oZ4dOprMnHI&t=2746s
A season prior, or even earlier in the year, Wilson would have gotten beat. Not only does he keep his man in front, he also makes the steal. Again, this was against one of Providence’s guards, not a plodding forward. Just looking at the official stats, we see that Wilson doubled his steal output from 2021 to 2022. This tells some of the story regarding his defensive improvement. But there is more here.
Value Stats
First, we will compare Wilson’s offensive stats from 2021 to 2022.

The columns can be understood thusly. Off Eff is Wilson’s offensive efficiency. He was more efficient in 2022. PtsAF/gm is Points Accounted for per game. This takes into account all points scored and assisted, while recognizing the added value of an unassisted basket vs. a basket the player was assisted on. In 2021 Wilson produced more points per game than in 2022. TS% is a version of true shooting percentage, with Wilson shooting better overall in 2022. Both ShotFreq and Impact look at the player’s usage, with 20% being an average usage. The team needed more offense from Wilson during his freshman season than they did during his sophomore campaign. The final number tells the whole story. Wilson’s offensive value was steady between seasons. He produced about 1 point per game offensively above that of a bubble-level player. He was more efficient with less volume in 2022 when compared to 2021.

Looking at defense, we see that Wilson’s Def Eff (defensive efficiency) improved immensely. The next columns tell us why. In 2021 he gave up 13.5 points per 60 possession while on defense, a number which improved to 11.0 points per 60 in 2022. The possession winner columns, PW/gm and PW/60, indicate that his rebounding/steal/forced turnover numbers were basically flat. The last column shows that Wilson went from a negative-value defender to a solidly positive-value one. Such a jump is rare.

2023 Projections
Without a doubt, this season Jalen will again be asked to take on a larger scoring load. Bart Torvik projects him to average 16.0 PPG. Given an increase in usage, his offensive value should jump as long as he can remain somewhat efficient. We project him to be +1.45 on offense, which would be about a 1/2-point increase. This is a conservative estimate which acknowledges that opponents will focus on stopping him more now that he is the primary threat on offense.
For defense, we project him to be +1.34. This is essentially the same as last season. It’s clear that he made gains defensively, primarily in the areas of lateral quickness and on-ball defense. For him to add more defensive value this season would require additional improvements on defense. But he is already a good rebounder. Perhaps in steals or forced turnovers? Given his position, this is unlikely.
Another consideration is that Wilson’s defense might take a step back as he takes on more of a scoring load. This isn’t uncommon to see. It happened to Sherron Collins in his junior season (2009) and Devon Dotson in his sophomore season (2020). As a player expends more energy on the offensive end, he has less to give on defense.
At +2.79, Jalen Wilson’s projected PPG AB +/- is +0.48 from 2022 and +2.15 from 2021. This isn’t a huge leap from last season, but it’s still a decent-size jump from his freshman year. Bill Self said that Wilson needed to have an all-American type year for Kansas to be as successful as it wants to be, which we can take to mean winning the conference and earning a top 2 seed in order to have decent odds at making a Final Four run. We certainly agree. The play of Jalen Wilson will determine a lot with regards to how Kansas does this year.
