Bill Lazor's job first and foremost was to install a system to fit the players on the field. A large portion of his hiring was centered around his coaching of a related offensive tree, and his work with quarterbacks, and he's failed in both regards. Even if Ryan Tannehill is a failed prospect that will have to be replaced, Lazor's job is to get the most out of him. He's totally failed in that regard, and instead we've got a player who is regressing at a critical part of his career. We're watching Ryan Tannehill handle multiple aspects of his job markedly worse than he did with the Dolphins in the past, and that's on Lazor. For some reason, we've tossed wholesale a wide variety of passing concepts, route combinations, and plays that worked well in the past. If they were things that violated the orthodoxy of the offensive system we chose to install, that'd be one thing, but they're not. The out-breaking routes that Tannehill excelled at are de-emphasized. Bread and butter WCO concepts that shouldn't really be off the table for schematic reasons are missing. Charles Clay and Brian Hartline are missing in action. Ryan Tannehill is struggling with his new footwork. The receivers are struggling to properly run there routes. The quarterback and receivers are quite frequently having issues where they're both not making the right reads. Those are teaching issues, and that buck ultimately stops with Lazor on that. He's essentially the quarterbacks coach, with the Dolphins choosing to retain Zac Taylor, whose qualifications are based more on marriage than skill.
