I have a QB with a promised So start. I have started him in 9 out of 10 games this season (I had a very competitive one and I played my Sr QB for the entire game). No issues yet, but the question is, how many games can I have the Sr start without this So being ****** off?
I have a very competitive to close conference schedule, plus I will then have the CC and the playoffs... Do these post-season games count or is the promised start only for the regular season? Will he get ****** off and lose a chunk of WE if I play my Sr QB in the playoffs??? I definitely want to start my Sr in the playoffs lol

My understanding is that the post-season anything goes promise wise...

I don't think playoffs/bowls matter, but don't quote me on that.  Anything up to that is up to the player and is random.  He may get ****** for missing only one start, he may get ****** for missing more than a certain number of starts in a season, or he may only get ****** if he misses a certain number of starts in a row.
