I honestly think that a lot of the concerns about Jaylen Brown are premature at this point. Reason being that I actually see an almost uncanny number of parallels between Brown and Andrew Wiggins:
1: PhysicalAt the Hoops Summit (the most recent pre-draft camp where both players got measured) Brown measured at 6' 6.5" with a 7' 0.5" wingspan, and Wiggins measured at 6' 7" with a 7' 0" wingspan.
Both players were praised for their elite athleticism - in fact both were labelled as the top athlete in their respective draft class.
Both were very young (Wiggins 18, Brown 19).
Wiggins is no doubt a little bit more impressive as a run/jump athlete then Brown is, but then Brown is almost 25 pounds heavier, and he's probably twice as strong because that extra weight seems to be all muscle.
So physically, they are pretty much on par overall.
2. StatsWiggins' Per 40 Minute Freshman stats:
20.8 Pts
7.1 Reb
1.9 Ast
1.4 Stl
1.2 Blk
2.8 TO
3.3 PF
44.8% FG
34.1% 3PT

Brown's Per 40 Minute Freshman stats:
21.2 Pts

0.9 Blk
4.5 TO
4.6 PF
43.1% FG
29.4% 3PT
65.4% FT
57.4% FTR
Those are VERY similar stat lines right there, overall.
3: Skill SetBoth guys were known as athletic freaks who loved to drive to the basket and loved to finish above the rim.
Both were questioned for their lack outside shooting, limited ball handling skills, questionable court feel, questionable decision making.
Both were seen as good rebounders with high defensive upside.
Wiggins' game wasn't quite as raw as Brown's in college - this can be seen in his better shooting percentages, lower turnover numbers, lower foul numbers, etc. Still a lot of similarities.
4: IntangiblesWiggins was always questioned for his lack of motor, swagger and general aggressiveness on the court - many people questioned whether he had leadership ability, and whether he had that "Alpha dog" personality (much like people wonder with Simmons today).
I don't think anybody has to worry about those things with Brown, because swagger, motor and toughness are things he has almost
too much of.
So before people get too concerned about Jaylen's limitations and his raw nature, I suggest having a look at Andrew Wiggins. He was a very raw athletic swingman who many people felt would take at least 2 years of development before he would actually be able to produce at a high level. Yet he exploded on to the NBA scene, took the ROY award, and averaged 18+ PPG over his first two seasons.
He had a pretty weak summer league showing too - worse then Brown's, from memory.
Just goes to show, you really don't know what to expect!
