QB wear and tear... only made it 9 games

Title says it all.  

Im using default wear and tear settings basically.  Bumped hit stick a bit and impact block.

Anyway, my QB, who is a dual threat, only made it nine games, then his season wear and tear is so bad he plays like 3 plays and then is out the rest of the game.  Thats last three regular season games and bowl game. 

I run it some with him, but not a ton.  Took a normal amount of sacks.   Is this normal for others?  How would an option QB make it through a season?  Really frustrating to me.  And even though he only plays 3 plays and then sits, the next week he hasnt recovered at all.

I use two RBs and they both have moderate wear and tear, which is fine.  I have a LB with moderate wear and tear.  I dont mind the system, but my QB missing ?

Anyone else have this issue?  Any advice/help?  What do others do to avoid this?  Should I turn down wear and tear sliders?

Thanks for the help!
