I have not settled on the "comp" path. You are putting words in my mouth.
I have settled on the meeting whatever the best offer would be from another team, and not going a dollar higher than that. Granted, no way to know what that number is, it is the GMs job to get there, and that is part of the negotiation.
You seem to believe if tua was a free agent right now there would be other teams lined up to give him the 5 and 275 based on the "comps" you believe in.
I do not think there would be other teams lined up to do that. I do not think other teams will "comp" Tua to Burrow and Mahomes.
I think Tua's open market value is a fair bit lower than the 5 and $275mm, and all the guarantees and other things that come along with the 5 and $275mm contract.
Side point, I do think the QB deals have become stupid, and self destructive. There is only one guy that has proven he can carry the team with that type of deal, which is Mahomes. The teams handing out these deals, I think some of them are making marketing decisions. They know they can be OK, and entertaining, and are willing to forego winning the SB and are content with having a good product on the field that can make a little noise. I understand why teams are OK with that, from a pure business perspective. Same with GMs and coaches. They keep their jobs in that circumstance. And the owners are pretty happy too. Stadium is full, and fans are not b*tching about them.
