I think Tannehill will be okay; he just is going to take time to develop, and that is not well liked in today's win now NFL. He sees his mistakes magnified because the offense (mostly the running game) sucks. I don't know if that is due to the back, the line, the play-calling, etc... If Brady or Manning overthrows an open receiver, no big deal; they'll line up and probably do it again. He and Wallace are definitely not on the same page and I think some if it has to do with communication. When Tannehill calls a play, he runs that play. If Wallace lines up to run a short play and sees the coverage will allow him to get open deep, he's going deep, no matter the play call. They've got to figure out a way to communicate that to each other.
