I think my main complaint about the staff this year is the handling of redshirts. They talk about it a lot, but Rahmir has used 2 games for something like 10 plays. McCaffrey used one for one play, although like you mentioned I think the one play scenario caught them off guard and they'd told McCaffrey he was the guy if Vedral went down. And Chase/Nance aren't ready for any game action?
I know they want them to be fully prepared, but they're is nothing wrong with giving them a subset of the game plan to focus on. If it's only a couple games, the specific plays they're used for won't be enough for other teams to key on.
