Just judging from some of the old faces now scurrying out of the woodwork, IMO the biggest difference is that most Tannehill supporters believe he'd be better than Cutler for us, BUT will be rooting for Cutler to succeed and then confidently let the chips fall where they may next season.
Compared to that, I get the impression/opinion that most entrenched Tannehill detractors are secretly happy he went down and hoping that Cutler outperforms even his sterling 8 game stretch last season because their own egos and self-worth are so heavily invested in Tannehill's failure. They may be paying lip-service but in reality, for many of them, being proven right has been more important than team success.
Sure, I would hope that everybody is rooting for Cutler . . . but I do think the Tannehill supporters are extremely confident that Cutler won't peform up to Tannehill's "best stretch in 2016" and the idea of their being a possibility of letting the chips falling where they may really hasn't hit home and probably won't until Jay does it in the regular season at a high level . . . which is fair.
And you are right, there are people who are happy that Ryan is not behind center and they would take Jay Cutler, Colin Kapernick, Matt Moore, trade a first for Kirk Cousins, it doesn't matter. That group of fans were miserable during that 7-1 stretch which I find mind boggling but whatever.
16 years since a playoff win . . . I don't care who is behind there at this point . . . if they can play well and engineer a postseason victory . . . I'm all about that.
