I think Jonathan Martin will look better in training camp than in the OTA/Mini sessions. When everything's without pads and you have to essentially play strenuous patty-cake, you can end up isolating upper body strength. When you go full-out in pads, that's when you get your lower body more involved, and Martin will benefit from that.
Things I took away from OTA/Mini Camp:
1. Congemi's exactly right about the pace, but it has its benefits and drawbacks. One immediate benefit should be the Dolphins ready to get off to a fast start, especially at home in the heat, as they'll be highly conditioned by fast paced field activity. One immediate drawback could be seeming to run into a wall with several players that just aren't learning things properly because they need a slower pace in order to learn (see: Johnson, Chad).
2. Receivers unit is in trouble, outside of perhaps Brian Hartline, who really didn't participate in many OTAs/Minis due to "personal" surgery (could range anywhere from appendectomy to nut-ectomy). Chad Johnson came in and immediately looked like the alpha of the unit, only one that could impressively get open versus man and consistently catch the ball. That doesn't bode well because we still have zero clue whether Chad is going to learn the playbook, ESPECIALLY considering all of the calls that will be made at the line, and the pace they're trying to set.
3. Speaking of which, this offense is extremely portable. It's like Madden, any given play you can audible any/all of the routes at the line based on what you see in the defense. This has benefits and drawbacks as well. The benefits are obvious. The drawbacks are just as real. If you don't have the right guy making those calls at the line, he can ruin the shape of the offense by audibling too many route combinations that don't make sense, being predictable, etc. It also puts a lot of responsibility on the receivers, tight ends and backs to adjust to everything that is going on. One drawback is I don't expect Ryan Tannehill to make a serious showing in this QB competition, by virtue of the nature of the offense. I don't care if he already knows the name of each play, route, formation, etc. What he has yet to learn is how to call them and run them against NFL defenses, and that's going to take a lot of time.
4. Sean Smith will probably improve. Reshad Jones is looking like he'll improve. I like what I've been hearing about Karlos Dansby at Mike, I think he'll be very aggressive. Not much else you can tell about the defense this early.
5. The following position battles are trending the following directions at the moment: Artis Hicks over John Jerry (RG), Lydon Murtha over Jon Martin (RT), David Garrard over Matt Moore (QB), Legedu Naanee over Clyde Gates (WR4), Charles Clay over Michael Egnew (TE2), Koa Misi over Gary Guyton (SLB), Reshad Jones over Tyrone Culver (RS), Chris Clemons over Jimmy Wilson (LS).
