I think the expectations of the offense resuming to the beat of 2016 are very unrealistic. There are a lot of new players on O since then and it's not an overnight process to get everyone in sync. There will be struggles early on. If the unit can stay healthy, I think they will overcome.
It's so early in the process right now, expecting anything even remotely like a regular season rhythm is expecting too much, IMHO.
Let's take a look at these new pieces from general perspective:
Returning starters in this offense: Tannehill, Drake, Tunsil, Davis, James, Stills, Parker
Returning contributors in this offense: Larsen, Grey, Grant
New veteran starters/contributors: Sitton, Kilgore, Amendola/Wilson
Rookie starters/contributors: Gesicki, Smythe, Ballage
I'm fully expecting all of the returning players to resume the beat of 2016 with Tannehill at the helm … they're just not going all out yet, because they're getting in football shape and making sure they don't get injured.
The new veterans are likely doing similar things, although there will be a learning curve, especially for Kilgore (needs to call the OL) and Wilson (being used all across the formation). So those two may take a bit to get fully up to speed, I'll give you that. But Sitton played for Gase in Chicago and excelled, and he's playing the same role here, so I am expecting a plug and play. Amendola already appears to be on the same page with Tannehill and runs great routes. He's moved around before and been instantly-successful in the precision based Belichik/Brady offense, so I'm expecting him to be ready.
That really leaves us with the rookies. While Ballage doesn't seem to be an ideal 1st and 2nd down RB, he does seem tailor-made for the 3rd down role, and even if he suffers rookie mistakes (inevitable), he is likely to be an improvement on Damien Williams and Jay Ajayi in pass protection and receiving out of the backfield. I think Gase will focus on that and get the best out of him in those roles. So, I am expecting production from him, albeit over a limited amount of snaps.
The one area that will be very interesting and very 'wait-and-see' is the rookie TE's. Traditionally, rookie TE's have little effect. The speed of play, complexity of the offenses and sheer amount of things they get asked to do that are above and beyond what was asked of them in college, tends to make those guys play very hesitantly as rookies. The physical requirements in terms of strength, size, speed, and playing in space as blockers against the NFL's dominant edge athletes tends to make rookie TE's look just plain silly. They tend to be the poster-child for being posterized … and that's not particularly fun.
So yes, we'll definitely have some issues with our rookie TE's. But consider this … Gesicki is so insanely superior to the shells of players we got with Jordan Cameron or Julius Thomas, that even his flashes look to be a very sizable upgrade. Superior red zone threat and that will translate almost immediately. Superior seam threat, and while that may not prove super-productive initially, it will still scare the heck out of safeties, opening up run lanes and underneath passing routes. Smythe's role will be more limited, but we didn't really have particularly good TE play in 2016, so I'm not sure how much of a dropoff it will actually be.
All in all, are we seeing a team that is behind the curve, or are we just seeing a team that is pacing themselves for the regular season? Call me an optimist, but I'm thinking it's the latter.
Our best preseasons have often come before some very unimpressive regular seasons. Some of our worst preseasons have come before some of our best regular seasons. I'm not ready to predict team cohesiveness just yet, but even if I were, it's often hard to tell until the regular season starts.
