You aren't really a big picture guy, are you?
Putting aside the idea that it's not really a great idea to call a starting QB in his second year a "bust" instead of saying that he needs improvement in your opinion. Your analysis about Thursday's game overlooks shortcomings in the "talent" and the "defense". It's Tannehill's fault we can't run consistently or that we get a fumble at the end of a long run, or miss a 34 yard FG? It's Tannehill's fault that the defense allowed the Bengal offense to stay on the field for practically the whole 3rd quarter?
The whole team needs improvement. If the team were it would be at least 6 - 2, not 4 -4.
