Just to clarify, what do you mean by "day one"? I think that mean just the 1st round now. I believe the old days was rounds 1-3. Is the old way what you meant?
Edit: To the point about turnovers... if we want to see more picks from our CBs then Leavitt better run more zone coverage.
One thing I learned was that, while they may have a "Quarters", "Cover 6", or "Sky Cover 3" zone coverage concept called, certain CB/WR matchups could easily turn into a Man to Man situation, depending on what the outside #1 WR does as well as what the slot #2 does before the 8-10 yard threshold. Point being, the defensive coverage is, at times, dictated by what the offense does just as much as the call on the field.
Also, it's hard to play zone coverage if you're being aggressive and dialing up the blitz. This is especially relevant to CU because we seem to struggle getting consistent pressure with only 4 rushers. Therefore, extra guys are sent to generate pressure and it forces us to play M2M on the back end.
