I care far less about the strikeouts (though they're so prevalent it's hard to ignore them entirely) than I do the lack of discipline. If he wants to be a successful MLB player while missing the ball a lot when he swings, he needs to know when not to swing in the first place. It's impossible to become Rob Deer, Ryan Howard, Adam Dunn, or Jim Thome without the walk component. It not only makes them a much more valuable hitter overall through avoiding the out, it's an indication that they knew which pitches to wind up and jack out of the park. If you don't know which pitches to lay off, why would an MLB pitcher throw a pitch you can hit? This isn't AA or A+ where pitchers are constantly missing their spots and giving you something to juice. It's MLB, where pitchers will put the ball where they want and if you're not ready to lay off an unhittable pitch, it's going to lead to disastrous results. It took Carlos Gomez 5+ seasons to become a valuable player and the only reason teams tolerated him for that long was because of his defensive ability and ridiculous speed. A guy like Walker isn't going to 1700 plate appearances to figure it out like Gomez did between the Mets, Twins, and Brewers.
