Reason: I'll just get right down to it. At the first play of Preseason Game #1 the players' conditioning essentially = 0 (zero). The engine machetes players from right out the gate and who really needs that?
Honestly it should probably be more like 50% or less. Screw realism, the preseason is about finding out what your players can/can't do and it's hard to tell when your rookie takes an injury hit right away. I know, I know, injuries are a part of the game. I agree to an extent, but since we are playing a sim that isn't like the real thing anyway, I see no good reason to have a high preseason injury rate.
That's why I won't play AI without the punt block in the public leagues. Injury rate = a constant 100% + the AI's defensive structure = Zone Defense meant to drive you into deep negative in play familiarity.
You have to power mash back for survival. Oh and MFN-# leagues are loaded with AI teams, therefore, you'll be up against it a lot. AI = no work put in. Me = tons put in. Blast 'em to oblivion is my motto.
