Johnathon Givony who runs draftexpress has just gotten word that McGary is eligible for the 2012 draft. NBA scouts (who usually are barred from watching high schoolers) will be watching him at the National Prep Showcase this weekend. For those who don't know turns 20 in June of next year and if we were an international prospect we would have been eligible this year as he turned 19 before the draft.
Givony has him as is 33rd overall prospect (only HS senior on the list).
Just to be clear I haven't seen any articles, tweets, or rumors about him considering declaring next year but it's worth keeping an eye on him in case an agent or someone gets in his ear. It's also worth keeping an eye on the NBA negotiations as the owners are making a strong push to make two years mandatory out of high school before being eligible. If the owners get what they want McGary won't be eligible until 2013 at the earliest.
Again, not sounding the alarm. It's just something to keep an eye on.
