I see this off season as pushing all your chips into the middle of the table. The defense is being overhauled. If Ryan wasn't the guy, were there no other 3-4 defensive coordinators that could have kept the philosophy and not completely revamp the scheme? My concern is the time it will take to get up to speed for the players we retain. To play this sport it has to be second nature where your assignment puts you on every play. While there are some really good players, there will be a learning curve. This is why I was opposed to changing horses in mid stream. We all talk about the window of opportunity this team has. Meaning this squad. If Ryan was a distraction, then could they not have found another 3-4 coach and maintained a semblance of consistency in defense and still improve? I don't believe this was a prudent move by revamping the defense and then changing play callers to boot. And this discounts the fact that a retooling of some players will be necessary, which adds to the burden of making these changes. So either this will be a brilliant stroke of genius and the team will make the play-offs and be a force, or they will again be a mediocre team to poor. I just don't see these changes as positive, but more a gamble, and there will be no middle ground between feast or famine.
