I don't care as much about how well his swing looks if it works. I hate when people try to change someone's stance when it works as is. Production is what matters.
Didnt you say you care about what actually happens? Well that's why stats tell you. Looking at his swing and wondering how it will translate is a guess, not what really happened.
Guys like Youk and Pence wouldn't be where they are had people looked at them and not strongly analyzed their stats.
