Was taken at 29 as a speculative pick.Top 5 pick? Your joking right? Worth a 2nd rounder maximum.
The speculation looks like paying off, so you'd expect his value to improve a fair bit.
I don't really see the 'top 5 pick' talk playing out, but his value would be a fair bit better than 29, so I'd be thinking 1st round, and given that there seems to be a lot of interest maybe mid round.
That said, I expect he's be staying, and the delay is merely a typical move from his manager, who likes to draw things out as long as possible.
