I'm just finishing my first season of HD. One of my freshman players increased by 84 points this season and won conference freshman of the year. Given what seems to be a huge increase this season, is there an expected increase over the next few seasons or does it depend. For reference, his numbers are as follows (gain is in parenthesis):

Ath = 38 (9), Speed 48(7), Reb 10 (0), Def 19(1), SB 12(2), LP 14(0), PE 54(10), BH 70(12), Pass 56(6), WE 78(7), ST 86(17), DUR 59(13).

His Total is now 544 and he gained 84 during the season. I assume he is done for the year as my team is out and won't play in the national tournament, but there are a few more days, so maybe he will gain.

Anyway, any insight on future development would be appreciated?

Well it looks to me like next season you should expect normal improvement for PE and BH and little to none for everything else. Except for ST and DUR, those will increase.

What is normal improvement?

it basically depends on what his potential was before his first season. His good WE helped his increases this season.

For example he improved 10 points in Perimeter. If his potential was average he'll probably only be able to gain at most 8-9 more points in his career. Or his max perimeter may only see 2 or 3 additional points.

If he had high potential he may improve close to those same 10 points next season and maybe 20+ over the remainder of his career.
