stafford was 33 when he was traded. Lamar jackson is 26 and kyler murray is 25.
deshaun watson is also 26. ergo they are worth more than stafford.
were free to say "no thanks" but someone else will. that's what it will cost you to get a good, young, nfl qb on the trade market.
most of the teams that will be picking top 5 will likely need a qb, so they may not want to trade down.
