I never made excuses for Mariota and I was calling out Locker while everyone here was still in love with him. It's not about making excuses, it's about being subjective. Tannehill is not why we lost yesterday and he's not why we lost to Cinncy or the Steelers. He actually put us in a position to win against Pitt. His worst game was the Bears, which we won anyway.
He has two dropped picks that I can think of, maybe there was a third. That's part of the game. Mahomes has had defenders drop picks too. That's why those guys play defense. The receivers and TEs are supposed to catch the ball. Tanny has thrown some DIMES in the face of pressure only to result in drops. You can only get knocked down so many times. There is something to be said about being and rhythm and having momentum. Outside of Mahomes, you'd be hard pressed to plug-in another QB there and expect a significantly different result. Even Wilson. Look at his struggles so far.
Can he play better? Sure. But he's not reason why we lost. Blaming him is just the easy way out. AJ was a bigger culprit yesterday. Vrabel was #1.
