Let's focus on this for a second. Machado is a third baseman, he has 80 games at SS in MLB with a -3 UZR, he's on a -8 pace so far this year. If you want to try to stuff him at SS he probably isn't going to sink you, but I think there's a misconception about what he's actually good at defensively. Nolan Arenado makes some sweet plays to his right at the hot corner too, doesn't make him a good MLB SS. The last 3 years he's only about a +6 third baseman too, which not so coincidentally matches up to his offensive uptick(e.g. filling out/physical maturity). Also, Machado is only a small upgrade over TLS with the bat against RHP, but that's a more minor point. Especially since Zobrist and Happ also exist so you're really talking about the best of the 3 for a given matchup. Guessing this is probably a bad idea.... But what about sticking him at 2B and putting Javy at SS? I realize he's never played there in the majors, but he's played SS. Surely he could play 2B competently? If he's +3-5 at 3B and -3-5 at SS, it would stand to reason he'd probably be averagish at 2B for now. At that point you've basically paid all that money for Brian Dozier though.
