I never saw the Lugo play, but even if he didn't hustle, it's one example, even if it's a perfect example.
As for Francona, he's trying to set up his team for the postseason. Is he doing it in the most efficient way...probably not, but the theory is correct in my opinion.
If you're going to tell me that homefield advantage or an extra day off is more important then properly preparing your team for the postseason, then I strongly disagree. Remember, the Red Sox are a pretty banged up team. They should use this week and a half to their advantage.
