Once upon a time I thought Keenan Allen had this because of his better physicality than Cordarrelle Patterson. But as I saw more games and saw a lot more of what was going on more away from the ball, the physicality edge is still there but not as dramatic a difference as I once thought. Patterson is a big dude and doesn't mind getting physical with people. What's more, he's got a competitive spirit to him that you can sense on the tape, and to me that means that as he's taught better and put under a staff that demands more out of him, he'll be even more physical at the next level.
Now on the other hand I'm not sure the gears are in motion like you say for Miami to be a great team. We'll just have to see on that. I like Ryan Tannehill. I don't think he's going to jump up and suddenly be a Russell Wilson. I've always compared him to Joe Flacco. But as you can see, Flacco in his 5th year is now a Super Bowl-bound quarterback, so I don't mean offense when I say he's like a Flacco. I just think there's another level beyond Flacco (which Russell Wilson might ALREADY be at, honestly) and I'm not sure Tannehill will get to it.
But anyway the reason I'm not sure the gears are in motion as you say is the following.
The Dolphins have $46 million in expected cap room. They are expected to release Richard Marshall which will put them between $49-50 million, but they'll need $6-7 million for draft picks which puts them back down at $43 million. So they have $43 million in room and 5 picks in the first two days of the Draft to cover the following liabilities:
*WR Brandon Marshall (starter)
LT Jake Long (starter)
DT Randy Starks (starter)
CB Sean Smith (starter)
*CB Vontae Davis (starter)
RB Reggie Bush (starter)
WR Brian Hartline (starter)
TE Anthony Fasano (starter)
FS Chris Clemons (starter)
*DE Jason Taylor (situational pass rush)
DT Tony McDaniel (rotational)
*Note: Yes I'm aware that Brandon Marshall, Vontae Davis and Jason Taylor were lost a year ago but they remain liabilities because the front office never replaced them, and in fact in the cases of Marshall and Davis the compensation they arranged for their losses was for the most part shoved into this offseason (which is why we have 5 picks on days one and two and not just 3 like everyone else).
So they have $43 million in cap space and 5 draft picks to try and cover all of these liabilities. And that's if they don't voluntarily rip open more holes as they did a year ago. For example, I've had the feeling for a while they might not like Karlos Dansby after he publicly ripped the staff twice, once for cutting OchoCinco and a second time after the first NE game where Coyle was being questioned by the media for having Cam Wake and Jared Odrick off the field for a few snaps of the final back-breaking drive.
