I do think there is a decent case for this being a combination of flexibility and proactive decision making. Take this move, along with Prince, and the announcement about Lawrie and Gamel investigating new positions really does move the bar. Just a week ago we had all of this essentially pure fan wish casting about moving guys to get a better defensive alignment. I read this as pretty much a reshuffle of the bats after Prince is dealt. The flexibility is that Melvin seems to have set himself up to be able to acquire the best offense defense combo bat between OF, 1st, and 3rd after Prince leaves. He is even in a position to not necessarily having to acquire another player to replace Prince, just promoting from within and trying to focus on the rotation. It entirely reasonable to assume that Prince's bat won't be completely replaced (at least the near 1.000 OPS version), however I'd say most of the reshufflings of Gamel, Casey, Lawrie, and Hart have a higher defensive upside than any possibility where Prince is at first.
