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).
