I think a Keller trade would have to start with Knies. Just what I would assume at least

I could certainly see it. To me, Minten has similar upside and plays center (which I know isn't crucial for a team like Arizona/Utah given their prospect pools, but still solid value). I'd feel more strongly inclined to add Knies over Minten + Robertson if the Yotes were staying in Arizona

Arizona connection makes sense, he’d have to pray they’re still there though

Me personally would rather knies over minten, but maybe Arizona feels differently. Either way your on the right track with one of those players being involved in a hypothetical Keller trade
