I’d recommend reaching out to the owners. Worst case you get shot down but maybe they like it or offer you a counter. I think all trades are a little short but you already mentioned expecting to need to sweeten so fire them off and hope you get a conversation
I wouldn’t take any of these. However, Robinson and Montgomery for Conner alone could be a viable move since you are buying the injury risk and also moving a questionable WR right now.
CMC owner for sure won’t budge unless cook is in the deal, and I feel the same way about the Barkley owner even if Barkley is underperforming abit. The prices for these two will be too high in my opinion.
