From a defensive standpoint, I'd believe Stearns would likely stick with what he has given his history of maintaining strong defensive players up the middle with more offense-heavy players on the corner positions. With Cain still being a solid option out there, there's likely a good chance they keep him out there and punt the offense if it doesn't turn around/mix Taylor and others in for more looks until they bridge the gap for Frelick/Mitchell in 2023. Offense-wise, it would be an upgrade (even more so if you believe Laureano can still be the player he was in 2018-19). But being an all-around player and the Crew's potential need for more firepower in the lineup than defense, it feels more like a gamble on an uncertain offensive upgrade for 2.5 seasons when there may very well be a better bat at a corner spot for the same/similar package.
Not that I don't like Laureano - it's interesting, but I'd be hesitant until we see some regular plate appearances for him and see where he's at. I'd pass on the framed deal - it's a bit rich. But I definitely agree with the Frelick/Mitchell/Wiemer centerpiece since it would take a high-profile guy that's looking good in his reps in the minors. It would definitely take a couple additional mid-tier guys for the 2.5 years of control though.
