I’m thinking of it like this, you’re drafting an elite, game changing bat (that just happens to play first base), not a first baseman per se. The comp on him is Yordan Alvarez. You’d take him 1-1. Yeah, he may not offer much positional value (although he can play the OF too) but he has the makings of a superstar at the plate.
Plus, he does all the things the Sox are bad at an elite level for a college player. I’m talking not just bat to ball skills and power but swing decisions and pitch recognition.
