I am not concerned about the rest of the league but only what Tannehill is doing. Why must every qb follow the same growth curve of the rest of the league? At the end of the day, you hit the open guy for the score. He isn't doing it. Does that mean he sucks? Never said that. Does that mean I've lost faith in him? Nope. Does that mean things can't be fixed? I'd say some things can be. Do I believe accuracy is coachable? Nope. Can he read defenses better and have better anticipation of the receiver separation and break? Probably.
People need to stop being so damn butthurt when someone brings up something about a player and stop ostracizing him/her as someone who hates the player. You can like the upside of a player and believe there is something there but also criticize the things they need to improve. It really is ok.
I wonder why you think accuracy cannot be "coached" or improved upon?
