Were you comparing Dozier's base running before and after Molitor's arrival? Because my reading led me to believe you were looking at 2014 only. Also, you'd need to expand measurement to every Twin that got on base in 2014, not just Dozier. Finally, to see if there was an effect of Molitor on the Twins' base running, you 'd need to compare their leads/jumps/slides, etc. to other teams in baseball to control for broader innovations and changing approaches to base running in general. It's useful to look at video and compare a team's stats from year to year, but there are a whole mess of variables you need to control for if you're hoping to make some causal claim of Molitor's presence on the coaching staff. Just saying. While trying to bring quantitative analysis into the conversation is somewhat constructive, and you did present a really thoughtful discussion, I think to really determine the effects we're talking about here would quickly lead straight down a rabbit hole. Go Twins! Go Molitor!
