I would kind of like to see Williams through a little bit.
You keep Grandy for 2013
OF: Ichy, Grandy and Stanton
Then let Grandy walk like what happened to Swisher...I would hate to see Mason go but Stanton is the better player long term without a doubt. Banuelos is out all season anyway and you just bring him back with caution and shoot for 2016 with him. 13 out all year, 14 minor leagues, 15 minor leagues and by 2016 he would be ready for major league action....take it really slow....
I'd give them anything for Stanton. I still doubt they trade him though. If the D-Backs can't find the right package for Justin Upton, I doubt the Marlins can find one for Stanton.
I don't think the two situations are the same. Upton probably hasn't been dealt because noone is willing to meet Arizona's price. Stanton is younger, and already better than Upton, pretty much a legit star. And he is way cheaper than Upton. If the Marlins were serious about dealing him, he is exactly the guy a team would empty their farm to get.
If they do want to deal him, I'm sure there would be several teams lining up to meet the Marlins' price..
