Dolphins need an O-line before anyone else ... including Wallace, can be evaluated. I laugh when I read about Tannehill not going through progressions. When does he have time? They also need to play Moore so that Tannehill will live to see next year (Joke).
Most of us knew the O-line would be our undoing this season but who would have ever thought they would have brought down the whole freaking franchise?
I have to admit I have a knee jerk reaction when I watch Tannehill play and makes a bad throw. I admit I'm guilty of this alot. But you're right, the OL needs to be fixed before we can truly determine if he's not the answer, as much as I hate to say it. He does have an arm, stands big in the pocket, but his lack of line protection doesn't allow for him to always make the best read/decision.
The line on both sides of the ball allows for others on the team, LB, safeties (defensive side) and QB, playmakers (offensive side) to shine. Right now, the OL is bad, if not horrific, and this causes alot of problems.
