Apples to apples, if they both go 7 years, Rosario actually gets 6M more, under Seth's plan. I know Rosario just had a big year, and Kepler a down year, but I think big picture, Kepler still has the higher ceiling. He's a better defender and baserunner, and Rosario's lack of walks will always put a hard cap on his offensive ceiling. Yes, Kepler has to not be awful vs. lefties to hit that ceiling, but given he has hit them in the minors, there is hope he'll figure it out.
