As far as I can tell from a couple tweets, Trey is expecting a boy in June!!!
I'm not sure who the girl is, but I have seen a few of Trey's instagram photos with who I would assume to be a girlfriend. I think with Trey Jr, Timmy Hardaway III, and GR4 leading the way, we should be able to hang some banners. Maybe Beilein's grandson(s?) will be big and strong enough from the subs by this point to contribute as well, although they made have graduated already by this point.
