I'm not a fan of excuses. He chose to let the leadoff spot dictate his approach, Rickey Henderson never let that happen. If he wanted ot hit for more power he should have. And then they would have moved him down if they decided to do that. Personally I don't subscribe to power being wasted in the leadoff spot. Regardless of who's in front of you, you have a better than 50% chance most of your ABs come with empty bases. Take Justin who had Jason and Freddie (and garbage) hitting in front of him most of the season, he was still basically 50/50 on PA with runners on vs empty. And that's with Jason and Freddie hitting in front of him.
Lineup contstruction doesn't matter and hitters and managers need to accept it, bat your best hitters at the top of the lineup and split up lefties and righties as best as you can. Don't let them hold anything back, just hit.
