Only one way to know for sure and sending them to the minors or the bullpen ain't it. But how do you determine it then? Say you stick with Freddy in the rotation, and he continues to get rocked in three out of every four starts, but then throws a gem in the 4th one. Is that enough? All these guys are young, and everyone expected bumps in the road. I don't think anyone expected the whole highway to be full of potholes, though. That's on you then if what is happening doesn't fit your expectations. None of these guys was going to be a bona fide ace. That was never their pedigree. So yeah, let them get beat up and live with it.
