I think the offense will be up to speed by the 2nd game of the season.
I have heard other QB's say that coming back to their position after an injury, it was the first big hit they took in their first game back that clarified to them if they were really ready or not. I'm sure that Tannehill will not pay that first hit much attention at all. He has always shown toughness. He is recovering from an injury that most player recover from. He has always had a fire is inside of himself and that fire was used to focus on football and his recovery program last year. According to Gase, the game has slowed down for him. He recognizes what is in front of him and adjusts to it quickly.
It appears that the players for our offensive line have been identified, are in place and will be practicing together for the rest of the preseason. We should know after the 1st game if they are going to be better than before or not.
I see the defense taking a little longer, but it takes every teams defense a little longer since most teams offensive schemes aren't well documented until after the first 5 or 6 games of a new season have been played.
The real magic will appear as our offense begins to extend itself through the play book. I see our current offense as fast at most positions and anticipate fast play calling to help take advantage of all our speed. I believe our running game will be as strong as our passing game, and that the running game will be a mask for an extended passing attack.
When we, the fans, can't predict if our offensive lineup indicates a run or a pass then the offense has done its job.
When we see opponents defenses that are tired and confused, we will know that the offense has done its job.
When our defense is always attacking and not winded at the end of the game, we will know that our offense has done its job.
When we score more points than the other team we will know that this team has done its job.
I think all the above will be evident by our second game and become even more formidable as the season progresses, other teams offensives get defined and our playbook expands to allow us to address our opponents new offensive schemes.
