I would too, thats just it. 2K is putting themselves in this situation by their lack of change with the feature. What they face here is a situation where if they allowed you to edit the rookies faces however you wanted, it wouldn't match the pre-made pic that was created for that rookie... this would look odd because you could take that black rookie in the video and edit his skin color to make him white, yet you will still see that black rookie pic associated with the white rookie whenever they show his player card in menus/during the game.
Problem #2 would come into play if 2K said **** it, every prospect that the user changes automatically gets the black silhouette instead of the pre-made picture... now the problem is that most of the league would then have a black silhouette because I will most certainly want to edit most of the prospects in the game in some fashion weather it be hair/skin/looks for variety purposes.
The solution here would be for 2K to come up with a better way of showing the created players and rookies so that they are represented exactly how they look in the game... the only way to do that is to have the game take a realtime snap shot of out players. NBA Inside Drive did it on XBOX 1, I dont see why they cant do it now.
Lastly this is needed more now than ever before because we dont have a CHoops this year so trying to make accurate draft classes though editing them is very important. Not letting us change the look of the rookies is stupid and has rendered this whole feature useless now.
