Bradley's offense is inevitable.
He was a fine jump shooter at all levels prior to the NBA and has excellent form.
He struggled in limited time to find his shot until finally getting steady minutes. During the second half of the season when for the first time in his NBA career he got real minutes (34 games, 24.9 mpg, 845 total minutes) his shooting percentages were:
FG% 52.2
FT% 83.9
3P% 50.0
In college, his FG% was 'only' 43.2%, but that's because Barnes' offense had him primarily taking outside shots, wasting his ability to cut & drive to the hoop, imho. Nevertheless, he took a 3rd of his shots from outside the arc where his 3P% was a respectable 37.5%. Folks will then point to his low FT% of just 54.5% - but that's a symptom of small sample size. Because he was always playing on the perimeter he rarely took more than a free throw per game. So that sample size is based on about 40 total attempts.
His high-school and D-League numbers in 2010/11 were, imho, a better indicator of his true shooting abilities because in each case he got more consistent utilization and was more confident about his role in the offense. The D-League is on a par with upper level NCAA competition and when Bradley went there for 9 games in 2010/11 he ate it up. Getting a healthy 32.2 mpg, he averaged 17.1 & 5.2 assists, shooting 45.2% / 37% / 85.7%.
I have zero doubt that Bradley will prove to be a legitimate jump shooting threat in the NBA. Sure, he's not likely to continue to shoot 50% from 3PT land. But he's probably going to be around a 37-40% shooter from outside the arc, which is terrific.
Add to that his proven ability to run and cut and add in a better handle with more experience, and he eventually should be as dangerous on offense as he is on defense.
Remember, he is STILL only 21 years old! There is a good chance, depending on who we draft, that he will STILL be the youngest player on the team this next year.
His upside is still tremendous.
