DE Myles Garrett requested a trade [Myles Garrett signs new 5yr/$204.7 million extension with Browns]

So, have people got to grips with the terminology, now?

When a player 'seeks a trade', it means they're seeking a new deal (and of course more money), primarily from their existing team. It's rarely, if ever about winning.

When a player is 'given permission to seek a trade', it's their existing team saying 'good luck getting something better' and waiting for them to come back to sign their offer sheet, for example Stafford and the Rams. Again, it's about money.
