Pointed out exactly where they could've gotten the money from and the goalposts shift to 'nyeh, well, can't pay 2 CBs like that'.
The **** you can't. You stagger the cap hits so by the time McDuffie is eating significant cap hits Sneed is gone. You have the last two years of his rookie cap hits, the 5th year option, and some book cooking on the first year of his extension. Easily doable to keep two elite CBs that by extension made this defense one of the best in the league.
