How much better overall does your first team player have to be for you to sub at getting tired? How much of a performance drop is there while playing at the different levels? Has anyone made any observations?

I still tinker w/ this, but if I don't want my reserve in there for more than 15 minutes a game (especially if it's a freshman reserve that's not developed yet), and there's a strong starter in front of him, I'll play the starter in front of him at "getting tired".

A lot of other coaches, however, are successful keeping everyone at "fairly fresh", but that's not my strategy. 

This was recently changed so players won't suffer as much as a drop off when they are getting tired. I know when the engine first came out guys played very poorly when set to getting tired, but this could change things. I haven't tried it yet but I actually will be in my next set of games to see how it goes.

doesn't that kind of sound like its worse now after the change? Or is the beginning part of the arc lower than what the linear progression was?

Yea that's what I was referring to. No dac what it means is that when a player is "tired" they will play worse than they did before however when they are "fairly fresh" and "tiring" they will play better than they did before which is way more beneficial because not many coaches play their guys to the point they get "tired."

So this is actually another benefit to the SIMs who play everyone at "getting tired"?
