There's going to be players on the floor of that international game with the potential to go #1 in their respective drafts.. Charles Bassey and Rowan Barrett Jr have the best chance..
I've posted before that I think Bassey can go #1 and he's a better prospect than Favors was.. Here's some footage posted 2 days ago..

He averaged 21points, 14boards and 6 blocks a game this year as a freshman, and he hasn't been in the country for much more than 1 year..
Players like Oton Jankovic, Marko Pecarski and Filip Petrusev are all really highly thought of by European scouts, and might not be that far off..
I suspect 6'5" PG Pedro Nunes will end up in the 1st round too.
