I think Lurker did a good job of explaining this a few posts ago.
I've got film of a practice squad player at DT just blowing it up, sure it's only one play but he should've been given a chance over Harry,even though the coaching staff doesn't agree. Harry wasn't doing enough for this 3-0 team. He should have been replaced by this practice squad player all along! Hmmm, sounds familiar.
Edit: Yolo, I'm not saying this to say you are saying this.
