A look at Ryan Tannehill, Brock Osweiler, and Kirk Cousins at http://www.phinhub.blogspot.com. Lemme know what you all think!

I agree with what you had to say in regards to Cousins. He's a heady quarterback. He understands the game pretty well. The problem I have with him, is his inconsistent decision-making. He'll miss guys running wide open over the middle while opting for a deep route down the sideline that is blanketed by an over the top safety.
I'm not sure that's a coachable thing....he does a nice job if his first or second read is open, but progressing to after that I've found he struggles. Hot routes, he's excellent. I think he can make all the throws, but again he doesn't make them very consistently. I've seen him miss guys by a whole 5-10 yards.
