Joe was ahead of the curve on analytics, and fielding shifts. Things everyone does now, but few were doing at the time.
He kept those guys loose in an environment where plenty of uber-talented, All-Star rosters have crumbled under the pressure time and time again.
How many times did we see Cubs teams who were similarly talented get swept in the playoffs, or have something wild happen that led to the wheels falling off? More than I’d like to remember. Mentally, these guys were under crazy pressure… They could have easily folded after being down 1-3 in the Series. They were resilient despite a long history of great Cubs teams coming up small.
Did he ride Chapman hard? You bet. Who else was pitching great out of the pen? It’s not like he broke the guy. 10 years later, and he’s still throwing BBs, has never missed significant time.
Did he pull Hendricks too early? Possibly. You can neither prove or disprove what would have happened if he stayed in the game, but his splits in 2016 show a markedly worse pitcher after the 5th inning and/or 75 pitches. Hendricks had just issued a walk, which was a pretty un-Kyle thing to do with a lead and 2 outs. Kyle was in uncharted waters regarding IP in a season at that point. He went to Lester, his horse, for the lefty/lefty. Unfortunately, Jon wasn’t as efficient or precise as one would have hoped.
In the end, they won the dang game. Nothing else matters.
