Just for some fun, I found the thread early last season discussing Brown and comparing him to Jeff Green. I've updated the numbers below to include year 3. They are per 36.
Year 1
13.8 p, 5.9 r, 1.7 a, 0.9 s, 0.5 b, 1.8 t, 3.8 f - 50.7 2PT, 34.1 3PT, 68.5 FT (53.9 TS)
13.4 p, 6.1 r, 1.9 a, 0.7 s, 0.8 b, 2.5 t, 3.2 f - 44.4 2PT, 27.6 3PT, 74.4 FT (49.1 TS)
Year 2
17.0 p, 5.8 r, 1.9 a, 1.2 s, 0.4 b, 2.1 t, 3.0 f - 50.7 2PT, 39.5 3PT, 64.4 FT (56.2 TS)
16.2 p, 6.5 r, 1.9 a, 1.0 s, 0.4 b, 2.2 t, 2.5 f - 46.3 2PT, 38.9 3PT, 78.8 FT (53.6 TS)
Year 3
18.1 p, 5.9 r, 1.9 a, 1.3 s, 0.6 b, 1.9 t, 3.5 f - 52.9 2PT, 34.4 3PT, 65.8 FT (54.7 TS)
14.7 p, 5.8 r, 1.6 a, 1.2 s, 0.9 b, 1.6 t, 2.6 f - 50.3 2PT, 33.3 3PT, 74.0 FT (53.0 TS)
Brown's reduced role helped with his per 36 totals and he has started to separate a bit more from Green overall, but also looking at the numbers you can see a general lack of real growth from Brown from year 2 to year 3 which is concerning as many players take a pretty decent jump from year 2 to year 3. That said, not all do and get their big jump from year 3 to year 4. So hopefully Brown takes that latter path and reaches that next level.
