I love HD, but one of the things that's always bothered me about the game is the lack of opportunity to exploit certain on-court circumstances the way one would in real life (say, by running a play specifically designed to get the ball to the guy being guarded by the defender with 4 fouls...)
Here's one change I think they could do in that regard. Let the five fatigue categories represent a point total (for argument's sake...Fresh =5, Fairly fresh=4, Getting tired=3, Tired=2, Very tired =1) and add the total together at all times for the five players currently on the floor to get a "team fatigue" rating. Then give me a dropdown menu on the team game plan page that reads something like "When team fatigue rating exceeds opponent's by (dropdown menu for point margin here), run (offense) at (slowdown/normal/up tempo)."
This would allow coaches to take advantage of specific on-court circumstances that currently can't be accounted for with the tools we're given. I might not want to run uptempo against a team for a full game because I lack a sufficient stat advantage in my eyes. But if I can exploit a sub rotation situation where for a 2-3 minute surge my guys are fresher, then heck yes I'd like to be pushing it while my opponent's tongues are dragging the floor for that limited period of time.
Just a thought on a Tuesday morning...throwing it out there to see what others think.
