Once-greats in the twilight of their careers with expiring contracts rarely resign with the same team, because they will be offered much less than the last year of their prior contract AND some other team is going to overpay for them. It's pride, and a last chance cash grab - I honestly don't blame them for it.
Letting him go get paid double and getting to live in the Bay Area is honestly doing Jordy a favor.

Jordy was a great player for GB, but he wasn't worth 10M in his last season. We're laughing at Lazard's contract and (no offense to Lazard) he wasn't half the player Jordy was.

GB's entire WR corps made $10M last season (lol) and is the envy of many in the league.
