I'll say it again, and I'm sure not everyone will agree with this, but I think you have to tie Anthony Eyanson in with those guys too. I get the argument against it, because he is not directly related to that trade at all, but I think it's very plausible that the Sox do not have the money to sign him without the Phillips pick, which netted them 573,000 more money in the draft (after the Phillips signing).
That was the largest savings from any signing, and aside from their 11th rounder Barret Morgan who got 350K over slot Eyanson was their only other overslot guy, and there highest overslot signing. So I firmly believe you do not get Eyanson without the Phillips pick.
