Let's try something new and take the guys who are wearing # 50-99 play DB, maybe we will have more success? Seriously,some of you believe that we have the best talent every year. Coaches doing something new and radical, I like!
I like that the coaches are open to new ideas, and always looking for ways to get better. No defensive scheme is perfect, and if there was one, everyone would use it, and all games would be a 0-0 tie. Michigan State has made this scheme work well, and so it is known that it can work, but it is no doubt true that Michigan State has better athletes across the board than Ohio does. Furthermore, they have been working with this scheme a lot longer than Ohio has, so they have more experience with the intricacies of it, and what can go wrong.
First, let's talk about the differences between the new scheme (Cover-4) and the old scheme (Tampa-2):
CB - In the old scheme, the corners covered the flats, including screens, sweeps, and out patterns. On deep patterns they always had a safety for deep help. They played mostly facing the play, not so much on the receiver. As a result, they made a lot of tackles, but they also were well off the receiver and gave up a lot of uncontested short passes. In the new scheme, they play man on man, mostly, and have no deep help. They have their eyes on the receiver. In this scheme, they will make few tackles because that isn't their job.
S - In the old scheme, they simply had a deep zone. They provided deep help for the corners, and because they were back deep, also had to make tackles on runs that got by the front 7. In the new scheme they have primary cover responsibility if a slot receiver, RB, or TE goes deep, and otherwise play the run.
DL - In the old scheme, their responsibility was to hold positions and guard lanes, and to keep the offensive linemen off the linebackers. In the new scheme, their job is to penetrate and disrupt, and hopefully to force a quick pass before the receivers are able to break free of the man-on-man coverage.
OLB - In the old scheme, they played a shallow zone, and they had to flow laterally to the play. In the new scheme, their coverage area is wider, and goes all the way to the flat. They need to be very athletic. They have to be able to stop sweeps to their side, and also cover out patterns. They will make a lot of tackles in this scheme that used to be made by the corners.
MLB - Not much change. Still covers the middle of the field, and runs.
Because of the changed responsibilities, players will not be doing the same things that fans have seen them do in the past. The corners will not be making as many tackles. The corners will get beaten more often, since they have no help, and that will especially happen if the defensive line isn't able to penetrate. The OLB's will need to be very athletic because their coverage area is very wide.
The goal of the old defense was to give up 4-5 yards every play, but no big plays. It was a bend-but-don't break philosophy. You allow teams to march down the field, and hope for mistake. A penalty, a fumble, and incomplete pass, any of them can end a drive. The goal of the new defense is to attack, and to disrupt. You contest every yard. The goal is more sacks, more tackles for losses, more 3 and outs.
Why did they make the switch? With passing becoming more and more efficient, when other teams did have an incomplete pass, or a penalty, they often were able to get the first down anyway. The bend-but-don't break philosophy was becoming increasingly ineffective. It is also harder and harder to recruit players to play a passive defense. They want to attack.
Has the new defense worked? At times, yes, and at times, no. It worked well at Kent, partially no doubt because they weren't expecting it. It also worked very well against Kentucky, after the first quarter. It worked well against EIU and Idaho, too, for the most part. It did not, however, work well against Marshall at all, and it was not that effective against CMU.
Is it time to throw out the new system? Personally, no, I don't think so. Like Billy, I'm happy to see the defensive coaches trying new things. I'm not surprised that there are some issues, though. I do expect the coaches to learn from debacles like Marshall, and from CMU, and I expect them to work with the players to improve, and work with the schemes to improve. Remember - they coaches have been working with the old scheme for 20-30 years, and with this new scheme for less than one year. I'm not overly surprised that there have been some issues. Any time you make a major change of this nature, there are going to be some problems along with some good things.
The one thing I did not like at CMU about the way the defense played was that I saw all too much effort at stripping the ball. I personally liked it when they were focusing on sound tackling, and I think they gave up some extra yards against CMU from failed attempts to strip the ball. Make the tackle first and foremost.
What about personnel? Does Ohio have the personnel for the switch? I think it starts with the defensive line, and against most MAC teams, Ohio's defensive line will be able to penetrate, and disrupt plays, which will take a lot of pressure off of the corners. Not surprisingly, the two teams that have had the most success against Ohio's new defense have one thing in common - a very good, veteran offensive line. CMU has the best offensive line in the MAC, so they were probably a difficult team for this defense to match up with. I think the defense will fare better against the rest of the schedule.
As for linebackers, Ohio has some very athletic OLB's, so I think Ohio is solid there. Converting former safeties, like Alexander, to OLB is the right approach, I think.
Does Ohio have the cornerbacks for the new scheme to work? I think Bass was better in the other defense, for example, while Wells is working better in this new one. I don't think Bass is doing a terrible job, personally, but he has been burned quite a few times, mostly in games when the defensive line hasn't been able to pressure the QB. I've seen fans blaming him for a lot of things that aren't his fault, however. There were a lot of cornerbacks in the new recruiting class, and hopefully some will good ones in this new system.
How about safeties? Safety is a place where Ohio has been ravaged by injuries. Carpenter, Jones, and Scipio are all out. I have noted that a lot of TD's have been thrown to guys lining up in the slot position, which is the man that is the safeties job to cover in the new system. That seems to be an area where Ohio can make some improvements to the defense.
