However, that's probably what the Mariners would ask for, and I think it would be more than fair. As great as their upside is, neither one is proven. Montero also loses some value because he will, in all likelihood, wind up being a DH. Smoak will develop and is an excellent fielding 1B. Banuelos has only had a cup of coffee in AA, so we've yet to see what he can do in the upper levels of the minors. Meanwhile, Felix is arguably the best pitcher in baseball, and he's only 25 (or will be in a few days).
