If you can sell that player for enough money that paying the players salary for the length of time it will take to get it back to 97% of the money being yours then do that, however i dont think you will get that with your players. so selling for any profit ASAP might be best.
I hope you make me eat my words, but i highly highly doubt that you will sell that 26yr old $6k PF for anywhere close to what you paid.
