Exactly: at this point the logical vote would be yes. The OP wants us to make an argument that Manuel, who only played 14 games and hasn't played since week four of this last season, is better at this point than a QB who has had the opportunity to improve over three full, uninterrupted seasons at QB. It is an argument that cannot be reasonably made. So, what exactly is this poll supposed to demonstrate? That Tannehill, (whose completion %, TD%, INT%, and QB rating were all worse in his first 14 games than Manuel's) improved with the opportunity to do so? That a QB who has played 48 games is better at this point than a QB who has played 14 games? Big surprise. Do we need a poll to figure that out?
My guess is that the primary purpose of this poll is to provide the OP with something he can use to rationalize his long standing dislike for Manuel.
