“The Bills and tight end Dawson Knox have agreed to a reworked contract that lessens his $14.4M cap hit this year, per source. More needed space for Buffalo.”
The “reworked” in the quote leads me to believe it’s a pay cut for Knox and not a classic restructure. Knox wouldn’t have had to agree to a restructure, but does have to sign off on a pay cut like this.
