Not that these tiny sample sizes mean much, but here are the run totals in games JD has not played:
7 (Apr 2)
7 (Apr 20)
1 (May 27)
0 (June 8)
4 (July 2)
19 runs in 5 games= 3.8 per game.
I'm convinced JD has made a significant impact on the hitters around him in the line-up. I'm not sure if it's more than all the other factors combined, like new coaches & managers and improved health by several hitters like Betts, Bogey $ Moreland, but I do think it mattered.
If you look at Betts, Bogey & Moreland last year, they all seemed to be doing very well before their injuries. Beni has taken off. One could argue he's a year older and wiser, but JD's influence seems to have made a major impact on his performance.
One could also look at Betts and Boegy when Papi was still here mashing. They had some down periods then as well, so it wasn't just 2017.
Is Betts' .812 and .803 OPS with Papi all that much better than the .803 in 2017 without Papi?
Bogey had worse years when Papi was here. He was at .660 in 2014 and not much better than 2017 (.746) in the two years prior (.776 and .802). Certainly, one could argue his injuries were enough to drop him from .776 and .802 to .746.
I've never been a big believer in a great hitter having a major impact on improving those around him, but I'm thinking it matters more than I previously believed it did.
