Maybe you dump him in a 12 team league............ Anything more that 12 teams go ahead and dump him. Some owner will gladly pick him up in 14, 16, 20 team leagues etc.... and then send you a thank you when his bat starts to pick up in early mid may like he has done his entire career. He is in the twilight but still offers usefull totals when he is hitting, and he will in about a month.
