Maybe because Callahan and Tomsula are widely seen as coaching gurus when it comes to OL and DL?
You can wonder, but you also have to take into account that guys like Dunbar, Fuller, made huge jumps with Gray at the helm. Moses when he started around was seen as a failure by most around here. Tomsula? Check Ioannidis and see the progress... You can't discard those facts as well...
Now as much as I hated our outting against the Colts, especially when it comes to our lines, I'm wondering if there's not more than what we've seen.
After all, players have to play games one at a time. They're supposed to focus on the next game, and not 2/3 games down the road. That's a recipe for failure (and maybe that did happen as our guys thought more about that Green Bay / Saints / Panthers games than the supposedly easy Colts).
Coaching on the other hand have to take the whole season into account. They have to find ways to come out of regular season with a ticket to the playoffs. You have to deal with your roster with its own strengths and weaknesses. And sometimes you know that you'll have trouble against some specific teams because their strengths do plays your weaknesses and that's not good a thing. Why do the Cowboys have our numbers with stunts and such? Why do the Colts went with it as well?
Because that's a recipe for success against our lines? Well Callahan's lines. If that was true, you'll have to believe that every DC would ask their DL to play it this way.
Except they don't.
Because their players aren't athletics enough? Because they aren't disciplined enough? Whatever, but most likely because they aren't that good at it, and if that fails, they're in for a long day.
So for a coach, is it really worth it to change everything you teach, every process, and change the way you play for one game if it can jeopardizes the whole season?
Answer here is no. You just don't do it. You go with what you do and try to come out of it with a W. But you knew from the beginning that this specific opponent would give you problems. But if your strategy is best for 10/12 opponents a season and bad against 4/6. You might just go as well with it, because you still have better chances of winning in the regular season.
OK, fans hates to see us lose to Dallas (I do too). But if I had a strategy that will make me lose to Dallas twice a year but will allow me to win the Superbowl each year, I'd do it in a heartbeat.
No proof, no whatever as coaches are not gonna tell you this straight (I'd really love to have a beer or two with Jay and talk football damn!), just thinking out loud on a stupid idea, as always.
But one that might have some truth in it.
