I took some stick for my appraisal so far of him last week, but I'm sticking with:
Game 1: Average
Game 2: Poor
Game 3: Good
Game 4: Abysmal (could be argued that he was only bad because no one got open all game but he really failed to make things happen in tough circumstances, which is a hard thing to do of course but not impossible to at least put up a bit of a fight)
Season as a whole for me right now, nothing much has changed for Tannehill, he's capable of the odd moment of brilliance, but on the whole continues to be middle of the road in general, with good scheming we could still make the playoffs with him but we simply can't afford to carry too many under performers like today. When we come up against the better teams we too often wilt and he's done nothing to prove to us that he can rise to the occasion and put the team on his back in these tougher games. He'll beat bad teams though more often than not with the odd win against the big boys but not often enough.
