I think his contract was actually 3 years.
And I'm not of the opinion that he "forgot how to run a defense," but I'm kinda starting to think that maybe the case might be any of the following:
1. Perhaps Brent Pry (his former Co-DC and PSU's current DC) deserved a LOT more credit for those Shoop defenses than he got credit for.
2. Shoop hasn't been as solely focused on running a defense since he got to Knoxville. Whether it's his desire to get a HC job, his contract dispute with PSU, or perhaps some personal issues we don't know about, maybe he's just not as dialed in as he was at VU/PSU.
3. He just doesn't have the same kind of cohesion with staff as he had at PSU/Vandy.
4. (This one is at least partly a factor, IMO, no matter how you slice it) Butch's offense is less compatible with Shoop's defense than Franklin's was. Franklin will slow down games a lot more than Butch and it allowed Shoop's defenders more time to get/stay fresh and/or allowed Shoop more time in the booth to get dialed in making adjustments.
5. Maybe some of the years he was coaching his units just had good luck that helped them look better than they were. In 2013 Vandy got to play UGA when they were down to just a white backup running back and JJ green and virtually no receivers, UF with their worst QB situation of the last 5 years maybe (and that's saying something), and UT with a freshman Dobbs that weighed 190 lbs soaking wet and hadn't developed much as a passer yet. The good offenses they played (Mizzou, aTm, and Ole Miss) scored 51,56, and 39 points against them. In 2014 the only two teams worth much of a damn that PSU played were OSU and MSU, and they both scored 31+ points.
Or of course maybe it's bits and pieces of a a number of these things. I haven't given up on him yet and I think he has a chance to put together a solid unit this year still. But idk if I think he ever was or will be an elite DC anymore.
You make some really good observations, although I agree with you that it's irresponsible to assume one or all of these are true with absolute certainty.
I do remember when we got Shoop, that while the majority of Penn State fans were crapping themselves, there were a level-headed few that talked about Pry, a long-time position coach under Shoop.
Your most striking point to me, was the difference in offensive tempo between Butch and Franklin. Penn State is now starting to speed up, as they did over last year when they found playmakers in Saquon Barkley and Trace McSorley. Before the emergence of those two, Penn State did have a bit of a slower gameplay, and that's when Shoop was at his best. Last year, they "dipped" to a respectable 37th total defense nationally.
With that comes my plea to corral expectations of this defense. Our tempo may not be as quick this year as it was with Dobbs at QB, but it'll still be quickly paced. Maybe it wasn't fair to assume we would be fielding top-10 defenses when we don't control the clock as much on average. That said, obviously 95th overall doesn't cut it.
We don't have a whole lot to go off of with these first two games, but the Florida game is definitely a show-me game for this defense. I noticed Franks had some pretty clean drop-backs against an excellent Michigan DL, and that's something that we simply cannot allow. As I was watching UF/Michigan, I thought Mac was dumb to take Franks out even though he was struggling to find a rhythm; he had still made some positive things happen earlier in the game. Watching Dormady a couple days later and seeing Butch leave him in was pretty heartening for me, and it shows me that Butch has a pretty good pulse on this offense.
Back to Shoop, though. I agree with everyone here-- we'll know way more about how successful we'll be with him here after this game. I hope to see some penetration and well timed blitzes, with hopefully a little less Justin Martin, no offense to the kid.
