yes, but 6* means nothing for the most part. What makes them sellable is the Quality number. Get them as close to the next star as possible. OR give them an SA.

Those two things will make the difference. If I know that I will be selling them next season, I will hold onto the skill points and/or make sure they get as close to x9 or x4 Quality.

On my 17th level account, my worst player is a 4*, 98Q MC, 24yo, just gave him Dribbler last season (so he is much more sellable at this point). He is 17 skill points from 100Q and he has 37 skill points in the bank. I should give him the 16 skill points to make him available on the neg list and see what sort of stupid offers I get. IF I can get 2 or 3 tokens for him, I will sell him immediately, as I can buy a 5*, 18yo for one token usually.

Personally, I would take the hit, keep your 6* and see what the rest of the season brings, while you bank skill points and make them more sellable
