My thinking is that Alonso has no shot at 7. I think teams will max out at 5, if that. I just don't see a lot of competition.
NYMs first and foremost, but they have alternatives. No interest in competing against them.
The other 28 teams look like they have money, but no need. Or a need, but not enough money. Or a need + money, but with competing interests. I think we get him for four years, and maybe in the range of $100M/4. If Casas can get us an appropriate return, I'd make the move.
