As a very rough proxy, in Brooks’ career his range factor per 9 innings was 3.20 and league average was 3.09. In Adrian Beltre’s career, he averaged 2.78 and league average was 2.67. The .42 difference in league average equates to about 68 fewer chances per season. But interestingly, the low point in league RF/9 during Beltre’s career was 2.23 in 2013. It rebounded significantly after that, even though strikeouts were rising. That’s a tough one to explain.
As to who is a five-tool player, it all depends what you mean. Does the player have to be outstanding in all five areas, or is a little above average OK? If the latter, then sure I’d put Adam Jones in that category.
Being a five-tool player may be overrated, though. Frank Robinson didn’t have an above average arm. Does anyone think Jones was the better player? Maybe we need another category, excellent players with no glaring weakness. Frank fits that category.
