"...according to research performed by Fangraphs.com, there has been minimal correlation over the last 30 years between the number of bases a team steals and the team's winning percentage.
On a scale where zero means there is no correlation between two variables, a team's stolen-base total and its winning percentage score a factor of just 0.12. Put simply, how many bases a team steals says very little about how often it wins."
I would say that speed is probably more important at Citi field than elsewhere.
