I wasn't a huge fan of him coming out of college, but for a 7th rd pick he's a great low risk, high reward move.
A few thoughts to address some of the points brought up in this thread. Not saying I'm right but here goes:
1. He's a quarterback first. You draft projects like Pyror and change their position cause you get four years to mold that player. On a one year contract, there's too much of a process imo to change position and expect him to beat out anyone at tightend or WR. Maybe he'll play QB/WR but I'd say he's a QB above all else.
2. Tjack's salary does not guarantee him a roster spot. They showed with Flynn and the Whitehurst deal, adding talent at the quarterback position comes with a price of doing business. If Pryor beats him out (small chance imo), they will cut Jackson if they only want two QBs.
3. They kept BJ Daniels for a number of weeks on the roster as a #3 last year. Though they mostly have kept two QBs, it's not unprecedented to keep three.
4. If Pryor plays well as a #3, I could see him offered a small fair 2 year contract to continue his development as Wilson's backup. If Pryor is smart he'll see the benefits of a system that can showcase his talents for when he hits free agency.
5. Giving up the last 7th rd pick costs little in opportunity costs imo. Seattle has done very well attracting UDFA because Carroll has a reputation for competition and letting the best man win. That's more than other coaches will do. Additionally, Seattle can on purpose finish the draft weak at a certain position knowing that will attract UDFAs. They did this last year at the linebacker position and sign a few good players because of it.
6. Pryor's upside is higher than any QB available after the first 5 rounds. This is a good example of comparing him against what QBs would have been around in the later rounds and getting the superior player.
