Vlad can hit a laser 117 mph off the bat right over the right fielder's head off the wall and have it bounce back hard right to the right fielder and he's on first. It's an advance attempt because of where the ball hit. He would have gotten thrown out if he had tried to advance. His base running stats in that scenario take a hit for making the right decision. Organizations can have third base coaches that hold up guys at third far too often and players base running stats will suffer. Vlad makes some boneheaded mistakes on the basepaths, but he's probably not as bad as what it says on Fangraphs.
FWAR is not the perfect stat. Roster construction on a team matters. The Yankees were second and won 94 games. Cleveland was 13 and won 92 games. The Tigers were 15th in team WAR and made the playoffs. The Braves were 5th in team war and barely made the playoffs. People look at the Gimenez trade and say, well the Jays got a win or two better. We're paying 19 mil a season and we didn't address what the roster needed. If we were chalk full off offense that would have been one thing, but we desperately need home runs. Committing that amount of dollars and not addressing what the roster construction required was the problem. We might climb the fantasy FWAR standings, but we're not winning more games until we address the lack of offense.
