The Ravens are in a similar spot to where the Packers have been for a couple years.
It's easy to let pride take over and make it personal. That's what the Packers did with Rodgers.
He wanted out, they wanted him to retire. Now he has them over a barrel and they have nothing to show for it. He'll likely force his way out this time.
Ravens should make the smart move. Lamar has reached his ceiling, imo. He's an electric player, but he's starting to miss games late in the year due to his playing style. His value right now is at its peak.
Trade him for a bunch of 1st round picks/players. Don't try to prove something about how tough you are by forcing Lamar to bend to your will.
In the end the player is always going to win that pissing match.
