Half the QB's taken in the first round are a bust, it's the most difficult position to play in sports and do it at a high level. This idea you and others keep throwing out there that the team will turn on the organization if they do not sign Purdy, is wrong, they want a QB that can help them win, it does not matter who it it. Trading 3 draft picks from Lance was a mistake, but it was a mistake for the Bears to trade up and take the kid from UNC instead of Mahomes. Hell, go back and watch the Mahomes pick, and the NFL guys are shocked, they are saying "they did not take Watson."
Purdy will be signed, he is not worth in my opinion $50 million a year, but teams over pay QB's all the time. Just because they do not reach an agreement this seasons, does not mean they are never going to reach one, teams Franchise tag players every year and then turn around and sign him to a long term deal, in the future. Hell Baltimore let Jackson shop himself around, and then signed him to a long term deal. No one really knows the value of Purdy, he is not taught of as top 5 QB, now is he a top 10 or top 15 is the question. Top 5 QB that every GM would take over Purdy, Mahomes, Allen, Lamar, Barrows and Hurts, the kid from Washington is moving up the ranks. Purdy is in the 2nd group of QBs.
