Until we actually have a decent option to replace him with, not throwing half the team's cap at Cousins or Bradford. Bridgewater was the only option this year I would even consider, and I doubt he wanted to come here without any chance of starting.
Don't get me wrong, I'm very low on Tannehill right now, but I do consider it possible he could become great with a proper team. I certainly see the odds of that being a lot lower than I thought at the beginning of the season, but I wouldn't say they are zero.
The real travesty is that despite spending nothing on the QB position since Tannehill has been here, the FO STILL hasn't managed to build up a good team around him. What happens when we find that next "savior" for QB and bring him in, and then our oline proceeds to kill him and we ruin yet another shot at turning things around? This is why this franchise pisses me off, because they don't set themselves up for success.
