I assume you are talking about Chase Young. There were a number of Guards in FA who signed for more money than Chase Young, twice as much in some cases. So for a Rusher who was the No.2 pick in the draft, $10m really was a bargain bin signing and showed what the rest of the league thought of him.
I feel like the Saints are one of those shows where guys hit a Junkyard for parts to build a vehicle from scratch.
eg
14 Mar 2024 — Signings. Guard Robert Hunt, 5-year, $100 million contract. Guard Damien Lewis, 4-year, $53 million contract.
