Aroldis Chapman struck out 21 batters in 15 2/3 innings in the postseason, allowing only 11 hits, and he had moments of total dominance, when his 101 or 102 mph fastballs overwhelmed opponents.

But in the National League Championship Series and in the World Series, two of the relievers generally regarded as his performance peers -- Kenley Jansen of the Dodgers and Andrew Miller of the Indians -- pitched for teams the Cubs faced, and Chapman suffered in comparison in the eyes of rival evaluators.

By the end of the World Series, some scouts had concluded that Chapman isn't as comfortable pitching multiple innings as Jansen and Miller, and probably is best suited for working when he can be given a clean slate: no runners on at the start of an inning. Chapman has had eight postseason save opportunities in his career and has blown four of them, and in the 2016 playoffs and World Series, he allowed five of 11 inherited runners to score.
