I'll be honest...I don't like it.
What are the eligibility rules for your league? If Jesus is going to be a catcher-eligible player for three years, I think he should have some significant value. And after your 3-year run with him, he should have some serious trade potential. And Colby Lewis is a pretty solid arm.
Ortiz is a slugger...no doubt. But, just how much does he have left? Idk...maybe plenty but Jesus is a tough one for me.
Meanwhile...is your power really "that" bad with Fielder, Miggy, Han-Ram, Jacoby...and even a big upside guy like Moustakas? I wish my teams had that kind of "problem".
Bottom line: If you don't buy-in to the Jesus hype, then I think you can "afford" to do this. I just wonder if there isn't someone else in your league that would value Jesus/Colby more...in the form of a younger, bigger upside guy? And can he not at least "throw in" a few saves to help you there too if you do this deal? Soria's season could be in trouble so I tend to agree with him there (though, you'll be able to find a FA keeper at some point).
