Following all the recent talk about replacing Tannehill as a QB, it's been interesting noting what might seem to be the significant/most relevant needs in a great QB. In short, if you have to evaluate any potential QB, it would seem that the most important thing is the mind of the QB. The knock that seems to be on Tannehill is that he has the physical tools and the work ethic and toughness but doesn't make the best decision often enough. Of course, physical tools are important, but if you can have all the tools and it's still enough, then the mind takes priority and you find you need that magical combination of both. Now how to evaluate that? I guess you'd have to look at a big picture of the decisions being made by any prospect, and how well they read defences. The problem is, the NFL is different to college, and how much is the coach and how much is the QB? I'm sure none of this is new, and if it were something simple it would be easy to pick great QB's. Still, I think it's worth pointing it out because the vast majority of QB discussions I see or hear talk about physical tools or even scheme fit over the mental aspect. How much more should and can that feature in evaluations?
