In response to RedsoxProspects' comment:
I'm at the point that I almost always say no when I hear a Stanton trade proposal. Everyone thinks it will take a lot but it's still only 2-3 years of control of a guy who may well be not much better than Middlebrooks.
Call me crazy but it's real tough to bet on power bats sometimes. They can be streaking and a guy with Stanton's body type can also get hurt.
Here are the 2014 WAR projections for Giancarlo Stanton and Will Middlebrooks from Steamer, Oliver and ZiPS as well as Oliver's five-year WAR projection:
GS S: 4.6, O: 6.1, Z: 4.3, O5: 32.1
WM S: 2.0, O: 2.1, Z: 1.8, O5: 10.0
And their MLB career lines:
GS 2002 PA, .265/.354/.535/.889, OPS+ 138
WM 660 PA, .254/.294/.462/.756, OPS+ 102
And their minor league career lines:
GS 1427 PA, .272/.365/.565/.931
WM 1902 PA, ..275/.332/.455/.788
Stanton is a year younger than Middlebrooks.
While Middy has some upside, Stanton can get better too.
I'd bet Stanton ends up with a career OPS 100 points or more higher than Middy.
