Looks like Cruz is gone they gave his #4 to the transfer Avery Graham. Although you can have a double # in college as long as one is off. and one is on def. Hatcher may not have made the grades and is headed to JUCO. They have 17 freshman listed so I would think that they are all headed to camp. Most should get redshirted though. Also two incoming freshman have same # as upperclassman but both are on the same side of the ball so expect them to be redshirted ( D' Amato & Marino ).
No mentioning of Cruz being let go, and he was mentioned by a few SBU insiders as early as a few weeks ago. He could very well have injured himself. Not uncommon to get a 2nd redshirt, and a medical is nearly always granted.
Also - if I was Avery Graham - I get to pick my number. Even if Cruz was on the roster, Graham would still be wearing #4. Graham didn't do much at Maryland, but he was still a touted transfer.
