"We disagree here. You get the major gains during the season when you are practicing every day and playing. Sure they can work on their craft during summer 7 on 7 player ran drills, but most improvement comes during the season. Something we haven't seen enough of. No one is expecting Nebraska to all of a sudden play perfect, but it would be nice to see noticeable improvement."
I would assume that during the season when you are practicing alot, you can make pretty good gains. Common sense tells you this. However, I do think Damon's point has a lot of truth in it. A given team in a given year mostly doesn't change it stripes. If you are playing every game close, you generally stop the run, and your pass defense is extremely suspect, then at the end of the year you probably aren't playing in a bunch of games where your pass defense is average, the bottom drops out of your run defense, and you start getting in high scoring shooting matches. Your blue print is more or less your blue print. We do see teams however, transform as a team and individually drastically in the off season.
Vrzal basically backed him up on this in Over Reaction. Saying basically these games are won or lost in the off season. Some discussion ensued saying that in a typical game week, you are wrapped up in game prep, and the "learning of football" takes place when there isn't an opponent on the schedule.
I agree 100% that you have to have some measure of progress and accountability. I think folks are struggling to find out what that measure should be, and what appropriate accountability is. I didn't look at the defensive numbers for Purdue, but by all accounts the numbers against NW were the best they had been all season? The coaches and the OWH were noting that the secondary was contesting more plays and so forth. Is it enough? "Fight on". And of course, accountability, which we mostly take to mean firing someone. Might putting on notice work? "we either have a Top 50 pass efficiency defense in 2016 or I'm getting a new secondary coach"
One might reasonably ask the question, if the coach has identified the mental part of the game as a chief struggle, does firing portions of the staff and introducing more new faces and instability, and yet another scheme, play to the issue identified? Or does retaining some stability with a secondary coach for one more year and seeing if any improvement takes place in the mental game make more sense?
I'm fine with either approach, because I think you could justify either.
