We are just looking at the first 5 years, champ, maybe you missed that?
Winfield's wOBA - .344
Heyward's wOBA - .342
Winfield's wRC+ - 116
Heyward's wRC+ - 115
Winfield's oWAR - 59.1
Heywards's o WAR - 72.1
Winfields' ISO - .151
Heyward's ISO - .165
Again.......for the first 5 years, Heyward has been just as good as Winfield offensively, you can argue he's actually been better.
It's the next seven that will make the difference for good or ill depending on where you sit on the comparison in the first place. Heyward has had one season better than the worst season Winfield had in years six through twelve of Winfield's career. Not saying Heyward cannot match those numbers, but Winfield was a pretty awesome force in his prime.
I watched Winfield up close when he played for the University of Minnesota. Saw him live several times (both on the baseball diamond and the basketball court). Just an absolutely stellar athlete. I saw him leg out a triple and it was like he only took two strides between second and third base (although I know he took more). And he pitched as well as playing RF. This was in an era before strength training (not that Winfield needed any strength training), but he was totally ripped and, as such, really stood out.
