The Brewers would laugh in our face at an offer of Peraza, Sims, and CJ. Good grief. Sims is quickly running himself out of prospect status, and CJ is a terrible defensive 3B with no speed OPS'ing at .616 and hasn't hit .300 in OBP in 2 years. He has negative value.
Peraza would be the only thing they'd want in that deal, and that doesn't even begin to approach Lucroy's value.
Ah, exaggeration.
Lucroy is a sensational talent, but you've got to consider the 'mitigating factors'; age, cost, positional wear, health, etc.
Peraza/Sims/CJ is a solid deal. I highly doubt they ultimately get any better than a top prospect, former top prospect (who is scuffling, but could ostensibly rebound to form), and a perfectly useful MLB piece.
