Not a Tannehill fan but you get rid of him who do you replace him with?
Ok let me stop laughing and actually try and answer this question seriously since it seems like you may be serious about this.
But before I go ahead and answer I do need to state that in releasing Tannehill we are trying to replace a guy that lead us to zero playoff wins, never played in a playoff game, and is currently leading one of the worst offenses in the NFL. Ok so with that said.
You could replace him with a Teddy Bridgewater or Trevor Sieman or just let Fales start. Either way you ain't making the playoffs but you move on from Tannehills terrible contract and start to rebuild the team with that money. You can also draft a QB this year or next or both. For sure at least one of those years. Doesn't really matter what they do, Tannehill is guaranteed to eat up a lot of money and never win a game that matter.
