Dunno, I'm pretty close on both of them. Kepler has the advantage of age, defensive ability (which seems to be better than Rosario this year, and Max can cover CF better than Eddie), and polish/discipline. Rosario has the advantage of L/R splits, pure hitting ability, and current performance. I suspect they end up as similarly valuable players but get there very differently. I still believe Kepler probably has the higher ceiling, as it's hard to argue with plate discipline, especially as a player enters their prime.
