Out of curiosity, do you know this for a fact? Like, there's pretty much no way that a player and his agent would research every stat, every comparison, and every analysis and then pick the most positive things to use at the hearing? I would be shocked if, say, Lucroy was going to an arby hearing this week and he didn't have that Fangraphs piece printed in triplicate. But maybe I'm being totally naive. Arbitration rulings are based on Elias, which uses the crappy RBI type stats.
