I don't know if people here help with sim leagues much. But since their contracts are pretty hefty, I would probably in your shoes downgrade a pick trading either for expirings. Tinsley would be easier to trade though.
Thats the 1st sim league ? I have seen on this forum. I wish I could be of more help. I agree with b_roy7 though, Tinsley would be easier to move. If hughes gets traded to a terrible team his value could go up quite a bit and then I'd sell high soon thereafter.
