My honest take after some time to think about it. Some thoughts.
Seattle did not trade a pick to examine Pryor. We have enough 7th rounders and UDFA's on this team not to cheaply give them away. Any trade for Pryor would have included talks with both Pryor and his agent.
This is the ragged end of Pete getting his hands on college players he has seen since they were high school phenoms. Harvin, Pryor, both are superior athletes that it isn't easy to label the skill set.
The big question for me is position switch. Pryor and Rosenhaus have had at least 4 weeks now to understand that the NFL has very little interest in him as a QB. Pryor is facing a contract year where he makes only 705,000.00 and the prospect that any team that signs him to play QB will not be looking to give him anything but a 3rd QB deal. Financially, for 2014 at least, being open to showing his athleticism at other positions has to be on the table. Up to now, Pryor has been adamant that he is not only a QB, but a starter. It was Pryor who demanded the trade when Schaub was signed. Whether he did so under advice from Drew is unclear, but I doubt that is the case. It has been 4 weeks since that demand, and the flood of phone calls likely expected by Pryor never materialized. This isn't like his pro day, where 17 teams showed up (Seattle was not one of them). IMO, the only reason besides pride Pryor has for wanting to be a starter at QB is money. 4 weeks facing the fact that the NFL is not lining up to give him a shot at QB money has to be a wake up call of sorts. Drew Rosenhaus may be a turd, but he is not an idiot about money. If Pryor wants an NFL payday, for 2015 at least it is not going to be at QB, but it could be at WR.
The Seattle front office has already publicly labeled him an athlete, not a QB. Pryor fits the Seattle prototype at WR. His NFL prospects at QB are dim, but at WR they are not. Seattle already has an athlete at WR who blurs positional lines, Harvin can impact a game without seeing hardly a single pass. To me, all signs point to similarly blurred lines positionally for Pryor. I expect in the coming days for some word to leak out about just such a thing.
