Let's first acknowledge the fact that any unemployed coach right now would have Houston at the top of their list. The reasons include an owner who doesn't meddle and passionate fans who fill the stadium. But past that, Cowher is not a good fit. His philosophy does not match the current schemes. There would be at least one or two rebuilding years before he would have the team he wants. On defense, I can't tell if he would keep Frank Bush or not. Bush's experience in coaching every position would always be of use, but Cowher would change the defense to a 3-4. In that scenario, he might use Barwin and Cushing as OLB's with Ryans and Diles in the middle. Okoye would be traded and we'd draft a huge NT. Mario and Smith of course would stay on the line. On offense, he'd reduce the ZBS to only a few plays and introduce power running. This means another year of rebuilding. We'd definitely get a big center and a guard in the draft. I have no idea how Schaub would adapt. Ultimately, there would be no way to avoid at least one rebuilding year. That is unless Cowher is fine with keeping what is in place, but that's highly doubtful. In my opinion, Mike Shanahan is the only coach that would keep things intact the way they are.
