Agreed. The times where you would probably do both in the corners is when Grandal needs to DH. When Abreu DH's, you can at least shift Vaughn to first. Nice to have the flexibility.
Yeah I think so too. Maybe DH all this week, play LF once a week after that (moving Vaughn, Abreu, or Moncada to DH for a game), start 2 of the 3 games in LF at Wrigley.
