Yep. Add him and Ohtani. I'd be fine trading for Alonso, but would want to exclude the top 5-6 guys from the deal. He's a 1B, only under control for one year, etc.
I waffle a lot on extending Bellinger. The back end of that contract is likely to look ugly. I was firmly against extending him because his batted ball data looks so meh, but I've softened on that. I guess it depends on how much confidence there is in PCA having immediate impact. Having Bellinger in there most certainly makes the '24 and '25 teams look a lot better, though.
