Not sure I see a lot of connection between Bourne and Thornton. Also, not sure I'd call Bourne a mistake. We didn't have any of Polk, Baker, Osborn on the roster at that point. Thornton and Boutte hadn't shown any level of competence yet (and honestly, still haven't to a huge degree). And outside free agents obviously didn't view us attractively. We had to have something in place. I think Bourne was/is a good signing for them in their situation.
That said, I also hope we trade him lol. Or more descriptively, I hope the young guys play well enough to where trading him is something we can realistically consider. I'm really hoping that by the end of the year the 5 young guys all look like NFL WRs (Douglas, Polk, Thornton, Baker, Boutte) to where Bourne and Osborn are no longer needed. And if either has trade value, take it.
