You must mean me, so I'm delighted you put me on the same level as Alex Cora.
Just so we know what we are arguing about, here again is what I wrote earlier. I think 80% of defense is the guy on the mound. This might explain why every MLB team without exception carries 12 pitchers on their 25 man rosters. That leaves 20% for the 9 guys, including the pitcher, defending against various flies, grounders, liners, bunts, etc. Divide 20% by 9 and you get a little over 2% of the defense depends on any given defender.
The offense depends on the 9 guys in the lineup--100%. Divide that by 9 and you get something over 10% for each guy in the lineup.
So a lineup player contributes 10% to the offense and 2% to the defense, so his bat is 5 times as important as his glove. You can probably make a case that some fielders, especially very good ones, are contributing more than 2%. In JBJ's case, maybe it's 3%, but I doubt seriously it's more than 4% because outfielders don't have as many total chances as infielders and catchers have more than anyone else.
So best case for JBJ is that his bat is 2.5 times as important as his glove. This could explain why, season to date, he has played in the second most games of anyone on the team. Cora likes him in CF (occasionally RF, but not often).
As for last night, JBJ in CF could have made that grab that Beni just missed. Beni is actually faster afoot--this is not arguable--and he had to come a long way from right center field (batter was a lefty) to left centerfield. We can assume JBJ would have gotten a better jump on the ball, but I'm not so sure about the better route. The real question is how much closer to the wall--the ball did hit it on the fly--was JBJ willing to go vs. Beni because he clearly slowed a little when he got close and in fact ran into the green monster, but not hard into it.
Even assuming JBJ makes the grab, it saves one run. The score is still 5-5. So it's really hard for me to see how that missed grab cost the Sox the game. It did happen in the 4th inning, not the 8th or 9th.
Me, I blame Porcello for having his 2d straight lousy start and for letting a really weak hitter like Fowler hit one off the wall in left center field.
As for the lineup, Cora was clearly loading up with righty bats. The two lefties in the lineup, Beni and Devers, both scored and knocked in runs. Swihart was the only righty bat left on the bench besides Vazquez--Moreland and Holt are both lefty hitters. Is if fair for me to point out that this stupid, no good manager put in a lineup that scored 4 runs off the exact same pitcher who pitched a no-hitter against the Sox the last time he faced them? It seems to me you have a really weak case on the lineup because this one worked way better than I expected.
The guy who didn't work was Porcello. I blame him and no one else. I don't even blame Smith because the bullpen went 3 innings and gave up just 1 run and were far better than Porcello.
