If it were up to me I'd probably let Osa go (assuming he's asking for roughly 20/year) and then spread that over 2-3 guys like Dayo Odeyingbo, BJ Hill and EJ Speed.
But we all know damn good and well they would never go after FA's who cost actual money, so in that case I'm fine with them just overpaying for Osa and going from there.
There are 4 main ways to handle situations like this, 2 good and 2 bad.
1. Pay the player, back load the contract, and use the up front savings to pay other players and build the team.
2. Let the player walk, and use the money you saved to pay for a couple other solid but less expensive players to fill the position adequately.
And now the bad.
3. Pay the player with a bad contract where money is used as a crutch to not spend money elsewhere because you are absorbing it up front.
4. Let the player walk, collect the precious comp pick, and pocket the savings while blaming your lack of spending on a cap that you refuse to use to your advantage as all the successful teams do.
I "wonder" which path we'll take?
