If anyone doubts that defense is a major difference maker, tust look at the teams that have played in the World Series lately.
Yankees - 19th in UZR, Phillies - 8th in UZR
Rays - 1st in UZR, Phillies - 2nd in UZR
Red Sox - 7th in UZR, Rockies - 10th in UZR
Tigers - 3rd in UZR, Cardinals - 10th in UZR
White Sox - 4th in UZR, Astros - 11th in UZR
Red Sox - 29th in UZR, Cardinals - 8th in UZR
Only 2 out of 12 teams that made the World Series had poor defense. 9 of the 12 teams were in the top 1/3 of team UZR. And the only two teams that won the World Series with a poor defense scored over 900 runs, which isn't realistically in reach for us next year.
