I wrote about this in more detail recently. I don't love the Olson and Alonso comps because of the age difference, although there aren't many great comps out there in fairness. Vlad Jr. is on the other extreme since he was younger than Murakami will be when he reaches free agency. I don't know why everyone conveniently ignores that one during these conversations — maybe because Guerrero didn't end up reaching free agency himself, but at this (very early) point he is a much better hitter comparison for Murakami than any of these other guys. A 170 wRC+ is MVP-level good. Again, very early. It will ultimately come down to just how good he is. If he's the hitter we've seen through the first 23 games, he'll be closer to Vlad Jr. and will be long gone. If he's closer to that Naylor tier then he can reasonably be kept even with contract inflation + his off-field value. If he's a Pete Alonso-level hitter, I would be skeptical since he's younger and more valuable off the field. I know Alonso just got his deal, but if he were three years younger this free agency and had an outsized off-field revenue impact, he probably would've gotten more like 8/280
