How much behind can a player get if he does a week of ST though? 7 weeks of missed training until he reaches 25. Not a lot to talk about. And to give all of that at once then seems like something not many people do.
On the other hand, if he's 27 years old and has 8 stamina, it'll take a couple of seasons before his stamina drops enough that he'll actually go to the bench for more than six minutes a game if you run a Princeton.
