I've grown tired of the transition rhetoric offered up so often. It's as if no other team has changed their offensive coordinator and had some immediate success. And, of course, I'm not talking about Mike Martz first year success either.
Anyway, I'd be more concerned if we were talking about an offense filled with a bunch of rookies or 1st / 2nd year players as in years past. Those guys had to learn a new offense, how to be a pro, and the NFL game (coverages, routes, techniques, etc.) That shouldn't be the case in 2015. And it shouldn't be as much of an issue if Fisher actually gets the run-first, play-action offense he said he wanted to bring to St. Louis, IMO.
