That's the summary right there. Tannehill has been the ongoing disease. Very difficult to tell what Adam Gase is, when's he's saddled with Ryan Tannehill and an organization that is dense enough to believe in Ryan Tannehill.
Sam Darnold won't be 22 years old until June. So essentially Adam Gase is buying upside that he never owned in Miami. At the identical age that Darnold is now, Ryan Tannehill had thrown a grand total of 9 passes as a college quarterback.
Most NFL head coaches fail. That's the nature of the league. Go .500 then get fired and you are forever considered a bum. But Adam Gase won an extraordinary number of games he had no business winning. I've followed the franchise for 50 years and there has never been a stretch like that. Numerous times in Gase's tenure the theoretical win percentage at a given point in the game was less than 10%, yet the Dolphins pulled it out anyway. Often you'll go season after season without one example like that. Gase seemed to assume he was birthrighted for those wins. Didn't even act surprised.
And it was very puzzling to evaluate. His point differential was abysmal yet the won/loss record was far greater than the point differential suggested. His home record was bizarre positive given the caliber of team, but the road record and road stats were terrible for that level of team. Gase won a fantastic percentage of tight games but got blown out to amazing dependability, even by teams that don't blow anybody out, like the Bills in the finale.
I tend to think he is underrated. What is the old scout saying...don't tell me what a player can't do, tell me what he can do.
Adam Gase won so many unlikely games and so often was annoyed at the offense even when it scored a decent chunk of points, like high 20s. That was particularly evident in his first season of 2016. Once I saw that attitude I concluded that he probably has major reason to believe his schemes can win big once he has a top notch quarterback. Apparently Peyton Manning feels the same way and strongly recommended Gase to the Jets.
