Wins Above Replacement (WAR)

This is sometimes thought of as the hardest to figure out but it also tells the best tale. Bryant spent much of his career with great WAR. In 2017, it was over six. That means that having him on the roster over someone else they had to call up from AAA or the like means the team added six wins to their record. That's the difference between making the playoffs and not almost every year. In 2018, his WAR was not only a career low, it plummeted. The 1.9 was over four lower than his previous low.
