ROTY is the hardest one, beucase most of the time, rookies don't get minutes in league games, but they do get minutes in scrimmages/cups.
Or alternatively, because you are training them, they are getting 48 mins at one position, and often their stats are a bit.... well.... crap.
eg: This is my rookie so far this season.
Name, Games, Minutes, FG, 3PFG, FT, OR, RB, AST, TO, STL, BLK, FLS, Points, Rating.
Kelley Ballard 6 33.8 16-40 0.400 1-3 0.333 0-3 0.000 1.7 8.2 0.0 1.3 0.8 1.3 4.0 5.5 6.2
Not exactly the most impressive. 5.5 points per game,.... although the 8 rebounds is pretty nice!
But once im out of the cup, he won't play another league game, so he will probably max out at less than 10 games for the season. And taht will be common for all rookies in the league. In fact, i think there are probably less than half a dozen rookies actually playing minutes in league games in my division.
So whilst it would be nice, its kinda pointless ... know what I mean?
