Big 3

Let's say there's a run on QBs in the top 6 picks, as many mocks predict. Four QBs go in the top 5 or 6 picks, as well as two of Chubb, Barkley, and Nelson. Out of the big 3, who do you see as most likely and realistic to be there when the Bucs pick at #7? Who do you think is least likely to be there? For quite some time I thought Nelson would be the most likely, but my gut tells me if there's any of them left it'll be Barkley. Chubb is the least likely in my opinion. He could realistically go anywhere from #2 to #6. Who do you think will be most/least likely to be there at #7?
