Can someone help.Ive had the game a while now and have a problem with training my players.No matter how little i train them there injury proneness goes up and up.There skill levels never go up.What im i doing wrong.Ive tried resting them that does nothing.Even with a training center.

Any ideas

You need a couple of good coaches...as hard it is to get them , you can't beat the gameuntil you get at leats two descent coaches....I've got 2 coaches with a rating of 7/9 (around 70 % in all) and can't find any better, I'm on my 7th or 8th season now.
So that stinks!

If you happen to find good coaches train the players in fitness skills like endurance and such...that will make your players less injury proned!
