It's already happened a little -- even in Heyward's rookie year, when Cox was the manager. They wanted him to be more aggressive, to drive in more runs. Which I think is the stupidest thing you could tell a 21 year old rookie who's seeing major league pitching for the first time -- "go ahead, swing at MORE pitches than you're comfortable doing!"
The Braves are not an organization that
values OBP, or even appears to know that it
exists. Heyward's clear future is as a #3
guy, driving in the first two guys and getting
on base at close to a .400 clip for the RBI
guys behind him, but I can absolutely see
the Braves ruining him by trying to make him
a 5 hitter and telling him that his job isn't to
draw walks, it's to hit the ball hard and drive
in runs. Especially if Fredi sticks
around.
