I spoke with Demetrius' mom today, and she cleared a few things up for me. There was a rumor/post whatever you want to call it that had said Demetrius wasn't sure about his commitment, and that he was "working on it."
There was a slight mix up with Demetrius' enrollment with Michigan, but it has been cleared up. That was the issue, it wasn't that anyone was recruiting him harder, or anything along those lines. Everything has been straightened out, and his mom says Demetrius will be at Michigan in January.
