I think the only thing Booger should have done differently was use the non-exclusive tag to try and set the market for Prescott and his agent. Some team offers him a 4 X 35 but with a better guarantee and is willing to give up 2 1sts, now they have a decision to make but keeping him then becomes defense against the league.
I don't think they know Prescott's market and Lawrence, Elliott and Cooper were easier to slide into where they fit in the rankings and money. They went high on Elliott but were boxed in, much like they are now.
If this was a sign him or take Lawrence proposition, they might fell differently but even he's a risk. As the QB's get picked, the risk will rise and at 10 they're probably looking at best, Mac Jones, but more likely Lance, Mond or Trask.
The other part of this is having the owner as the GM and the possible embarrassment of letting Prescott walk and busting out on his replacement. I think that was one reason CIN took Burrow, that was the no brainer pick for them and they're owner is also the GM. Different ball game with the owner being the GM. I think Booger would rather overpay for Prescott than come up snake eyes with another QB. This is the same guy that tried to trade up for Lynch and was pissed at himself for not giving up more to get him after sleeping on it. He could have easily bumbles that pick and still be looking for a QB.
