From someone who's broken down every offensive snap by UMinn vs B10 opponents.... one view on what can be expected:
(With the HUGE caveat that one never knows to what degree a coach may adapt/mold/reshape his schemes to fit existing personnel and design.... and to what degree a coach will reshape existing personnel and designs to fit "his" schemes.... and only time will tell).
KC's offense will - largely - share some of the basic fundamentals of the existing PSU offense. I think everyone knows that.
Fundamentally, what will be the same:
1) A lot of "check with me" decisions at the LOS based on what they are seeing from the defensive alignment
2) A lot of read-option in the run game, and a decent mix of RPO
3) Making the D at least have to account for 11-on-11 (the threat of the QB as a ball-carrier)
4) Primarily a zone-blocking scheme (in general terms)
What will/might be different from the current offense, if KC brings what he has been doing at UMinn:
1) A lesser reliance on the QB as a ball-carrier. It will still be an option, but (if anything at all like what KC has done in the past) not nearly so much so as under Rahne.
My personal thought - that is a good thing
2) More predetermination (at the LOS) of "run" vs "pass". Its not like PSU - under Rahne - did a TON of true RPO.... but KC seems to do even less of it..... choosing instead, it appears, to make those determinations pre-snap.
That certainly allows the QB to reduce the amount of live read he is doing, play faster, and ask less of the QB (especially a younger, less experienced QB).
My personal thought - that is a good thing
3) More six and seven man protections. Pretty self-explanatory.
My personal thought - that is a good thing
4) Less straight drop in the passing game.
PSU actually runs (ran) a LOT of straight drop in their pass game (more than I think most folks would expect). KC - at least at UMinn - really tried to reduce the amount of straight drop (probably at least partially due to not having OLs that could be trusted in standard pass-pro) but instead threw the ball (quickly) a lot out of "RPO-looking" work from the OL (even when, I believe - based on what it looked like on the video, they were determining "pass" in their pre-snap reads).
Their difficulties - when they happened - arose when they were forced into obvious passing downs - because their OL simply wasn't very good in those situations.... so they schemed and play-called to minimize that.
My personal thought - KC will feel a little more comfortable including more straight drop (with a competent OL), but will still do a lot of work from the RPO look up front.... which I think is a good thing, and is very hard to defend.
That RPO look - even on what were probably pre-determined throws - absolutely drove the PSU D nuts (and most other teams they faced) - - - and they often had 2 or 3 linebackers (and even safeties) up in the line of scrimmage as Tanner Morgan was taking advantage of wide open passing lanes to slants and dig routes with zero underneath defenders.
5) More diversity - and heavier reliance - on getting the ball to the outside receivers. UMinn and PSU (under Rahne) were pretty much night-and-day in that regard.... enough said.
My personal thought - that is a good thing
6) Run game will be more TB reliant (as mentioned earlier) but still predicated primarily on inside and outside zone with read-option elements.
My personal thought - not much different, and having less of a threat from the QB CAN make things a bit easier on the D.... but so long as it is enough to "keep them honest" the benefit of fewer hits on the QB might be a long term plus (over the course of the season)
7) Run game may be less diversified than some of the things Rahne was beginning to sprinkle in (which I thought was Rahne's strongest area). KC did incorporate the occasional misdirection (including some limited stuff off of the jet-sweep motion)….. but he was pretty bread-and-butter with his run game - choosing to "keep the D honest" by being able to LOS check to the pass.
My personal thought - more or less a wash, and you can't do "everything" and do it well.... but may miss some of the tangential elements of the run game that were emerging under Rahne.
Miscellaneous:
- UMinn under KC did, of course, run some "under center". Will he bring that to PSU? IDK... and IDC (personally, I think its irrelevant - but some folks might jump for joy if they see it
)
- UMinn does run some traditional screen game - another thing that may cause some to jump for joy …. but they don't really use a full back
- UMinn does - on occasion use a "wildcat".... with a power running QB. That - they way they used it - can reduce some wear and tear on your #1 QB in obvious run situations, and I could see him doing the same here at PSU.
- KC is an EXCELLENT situational play-caller (much like Bill O'Brien). This was one of Rahne's weakest points...… so that should be a huge improvement. He also is quite aggressive (which may surprise some folks, given the overall history of UMinn over the last decade or so). Much like JMoorhead in that way. A huge improvement for PSU - if that continues.
That's about all I can think of - in broad strokes - OTTOMH, based on what I saw out of UMinn the last couple years.
