He had a better on base better than Saenz, so if Choi "couldn't get on base", then Saenz cannot either. And his slugging is 27 points better. That's about three total bases for every 100 at bats. Likewise, Choi's OBP wasn't much better, as he gets on base about one time more for every PA. But you disproved nothing in my post, and the Dodgers kept the guy who hit marginally better who is eight years older.
Not to mention, they do different things. Choi is noticeably better v. RHP, Saenz is noticeably better v. LHP. I don't see how that comparison you made added anything to your point.
