You know Tannehill has only a single ACL injury, right? The injury was never repaired and simply finished its tear. It’s not two separate injuries. Regardless, in no way would I be in favor of Alex Smith. At his best, he and Tannehill are a wash, and frankly, Tannehill last year showed he could be a better QB than Smith. As to Mayfield, I admit I only saw the bowl game, but he folded like a cheap suit under pressure. If that game is indicative of the player he is, he will be a bust at the NFL level.
