I disagree that it isn't in the market. I also disagree w/ the way you'd handle it. A contract averaging 8.5-9 mil/season is a legit offer, and about what his skills/production point towards.
What makes you think we have to pay at the top of the market for every player who comes up in FA?
The NFL salary cap for 2022 is 208.2 mil. 15 mil would be what, 7-8% of the cap? So, you think you have to pay an above average TE 8% of the available cap? Why?
I think you have your idea of paying players all screwed up!!!!!!
