All of those guys average 28-30 touchdowns a season, have super bowl rings, MVPs, etc...they can take care of the ball however they like. However, it's worth noting Tannehill fumbles at a much higher rate than all of those guys.
If Tannehill didn't take care of the ball, he wouldn't even be a starting QB right now. He'd be long gone. He doesn't have the offensive production that could outweigh any major flaws in his game. Tannehill is an accurate QB, doesn't make many bad decisions, he's mobile, and a good teammate. That said he's never thrown touchdowns at a major clip, it's unlikely he ever will. In today's league, I'm of the belief you need more offense than what he's been able to lead us to.
Every year we talked about 30~ touchdowns, bigger YPA, etc etc...never happened, and it's actually gotten worse, not better. Blame it on O-line, Gase, receivers, etc...it doesn't matter what you want to blame it on because now he's got health issues to boot.
For what he's going to cost I think we're best off either moving on or agreeing for him to take a pay-cut, and address the position in the offseason. At the very least a contract that accounts for the likelihood that he'll miss games. This whole shell game at QB situation is getting old. Our contingency plan sucked, and that's on Gase...but Tannehill isn't going to save us.
