Need some keeper league advice

New to a keeper league. 3 player keeper, you can Keep a player for 3 seasons max. Full PPR. I’m currently working on a trade to get Aaron Jones, Would you trade CMC for Zeke and a second round pick? I know cmc is great and especially in a full PPR is way better compared to Zeke but knowing I could go into next seasOn with possibly Zeke, Aaron Jones and an extra second is intriguing. Would stick with cmc? Do this trade? Is it enough to give up cmc? Thanks in advance!
