How about:
a.) Changing player's size/weight
I always set my player's size at his height with shoes. That means:
-KB is 6'7''/230
-KG is 7'1''/240 (he said that this is his height on many occassions)
-Darko is 7'1''/265
-J.R. Smith is 6'7/225
-Andre Iguodala is 6'7
-Kirk Hinrich is 6'4
-Vince Carter is 6'7/225
-Joe Johnson is 6'8
-Jonathan Bender is 7'1/240
-Tyson Chandler is 7'2/235
-Ben Gordon is 6'2
-Ben Wallace is 6'8
-Tayshuan Prince is 6'10
-Andris Biedrins is 7'0
-T-Mac is 6'9
-Bostjan Nachbar is 6'9
-Luke Walton is 6'9
-Nesterovich is 7'1
-Kirk Snyder is 6'7
-I read it somewhere that Kwame grew an inch and gained a couple of pounds, too.
...
b.) Doing something with stamina
A lot of potential franchise players (or at least future starters) have lousy stamina ratings. Sophomores (Darko) and rookies...
c.) Modify destiny rating
Put LeBron at 1, Darko at 0, Sasha Vujacic at 1,... Just read any of scouting reports and learn about player's potential.
d.) Change Beno Udrih into a monster.
I really like this guy. I mean, he looks like Steve Nash all over again. But in Live? His speed/quickness ratings are in 60'. C'mon... Same goes with Kirk Hinrich.
And merry Christmas.
