I'd go for Stanton, all-in. He's the franchise hitter we need if we want to replace Ortiz and legitimately contend again.
My GUESS is he would cost something along the lines of JBJ, ERod, Groome/Chavis (pick 1), and then 2 other solid 'B' caliber prospects. Boston then takes back most of Stanton's remaining contract.
I would really hope MIA eats up like 45M total so his remaining contract looks "better" at 10/250M. (Now he has 10/295M remaining).
Thing is, Miami would prefer getting back a young MLB player (like JBJ) AND pitching prospects, so they may want Groome. In that case, what good pitching prospects do we even have left besides Houck??
My biggest fear also is that they pull a "2015" and go for Stanton AND say, Hosmer (2 big bats with huge contracts). Yuck...
(by "2015", I mean when they made two big signings in Hanley and Sandoval which hasn't really worked out and Hanley has only been great 1 year, underwhelming the other 2)
I'm just not a big fan of Dombrowski. Like DET, he just empties farm systems, gives out big contracts you regret later on, win no World Series and then become mediocre with no farm system or good youth left (look at DET nowadays, with no farm and big contracts on "old guys" they want to move).
