From Gaby regarding these tweets:
My understanding is that this is a sort of call to rally the troops internally. Miami knows these next ten days or so that some big names will come off the board. There is still a lot of work to do with Jarquez Carter, DJ Pickett, Jaboree Antoine, and Vernell Brown, but Miami is rallying and know that they have to close in the fourth quarter to get these done. I wouldn't take it as gospel that Miami will land each of these kids, but moreso that they know there's a lot on the line.
This summer is also internally viewed as the "pre-season" so they know that one way or another their story on the recruiting trail this cycle will be based on what they do on Saturdays this fall.
A lot to be excited about but still a lot of work to do with said prospects.
