Believe it or not, that OF makes sense. With plus range for COF on either side of him, Griffey's decreased range can be hidden. If you stick him at a corner, he only gets help on one side. Plus, Vernon has the better arm for RF. This OF allows either Teixeira or Lee to DH, which maximizes the offensive potential of the team.
Francouer impressed in his debut, but his aggressiveness and lack of patience at the plate can be exploited by premiere pitchers, which is what he'll be getting all game long against the good teams in the competition. He'd be best utilized as a defensive replacement (Griffey out, Vernon to CF) when they have the lead late in games. And, despite his propensity to hack, the kid can hit, so he won't be an offensive blackhole of a replacement.
