I am going to try to touch on a few of your points, but I am a little bit confused because as we stand with the recruits listed above, I firmly believe we will have the top offensive line in the SEC next year and we will be known nationally for it.
First point of reference would be Octavius Jackson. Jackson is a OL known for getting down the field in run blocking and short passing plays. When he gets down the field he is a force to be reckoned with and one of the best at his level. That being said he obviously will need some work technically with the pass protection phase, but I believe the plan will be for him to red shirt this year along with Dillard to go through the workout program and learn some more of the technical skills from Davis.
On Dillard, I believe Michigan, who I am assuming you are referring to with the "school's up there" knew that he had no interest in going there and thus did not offer, along with their plethora of top tier guys. Now I am not going to argue that he is in the same level of guys like Dawson, Tunsil, etc. but he is a solid center/OG with tons of potential that will get time to perfect his skills.
Tyler Moore will be a Gator. Tyler Moore will start. Tyler Moore will be a beast.
Tunsil will not be a Gator. We like Moore better than Tunsil. So long Tunsil.
Trenton Brown has us leading at this moment and I also believe he will be a Gator and have a big presence on this line next year. As you said he has great size to play tackle and that is where he wants to play, a major reason he is rethinking UGA.
Lacy, Johnson, Denson, and Outlaw we have either cooled on them or they have cooled on us. Don't see any in this class. But that is just my opinion.
David Dawson is an enigma that was scared away from visiting when that news leaked near FNL. His Michigan coaches then were able to talk to him and get some of their other commits to do the same. Don't see him in this class.
That being said, if we can add Moore and Brown who are ready to play day 1, I think our line could be something special next year. After those two I think the last spot will be held for someone we want rather than just getting one more OL.
