Part of the struggle I see with Correa as well is that the Astros themselves may want to up their ante with him too.
They will have to pay a ransom to get him, and honestly as much as I'd love to see him in a Tiger uniform, not at too steep a price.
In terms of where he'd rather play, this is probably an overrated factor, but one selling point of coming to a Detroit would be that he would be THE guy here, not just another cog in murderers row with the Yankees.
I dont know if that matters for a lot of players tho. Probably not.
