Productive Outs, Hustle, and Smart Baseball, win games. If those are not factored into WAR, then that stat, is flawed. Good for quick reference. For those that like Stats.
Quick example: Machado, probably great WAR, one play in Series against Brewers, hit a grounder, didn't hustles to try t beat out Double Play.
Benni: Against Dodgers, 2 Outs, hits grounder to 3rd Baseman, bust his ass, down the line to beat out the throw to 1st. Next batter, Pearce, clears the bases with a Double. Was that factored into WAR for Benni?
My advice watch the games more. You'll see plays, that wins games.
