Eric states below as you'll see that its only his opinion (no sources or rumours, just a hunch) that Colangelo will use the 13th pick in a bigger move whether it involves Bosh or not.
Source - Click here13. Toronto - I will preface this by saying ... I have not spoken to anyone in the Raptors organization about this pick as of yet. So this is simply my opinion: I think this selection will be used in a bigger move (ie - a trade). Whether Chris Bosh stays or goes, I think Bryan Colangelo is going to be very active this summer and my gut tells me we could see a deal (big?) or two go down that involves this pick. We'll see as the next month or so unfolds.
