It is an all 2015 league so catchers are all 2015 catchers. Generally the arms are fairly split between As and C/Ds.
As a whole, I would say offense is overperforming on the average. League splits are .273/.336/.440/.776 Real life was .254/.317/.405/.721
In real life there were 3569 SB attempts over 165488 ABs or 1 every 46 ABs. We are averaging 20 SB attempts per 4073 ABs or 1 every 204 AB. I know that is not a perfect example but it's within the realm of meaningful. In real life there were 3569 SB attempts over 4858 games or .735 attempts per game. In our league, an average of 20 over 114 games or .175 per game.
Historically, in this progressive league, we shatter all of the RL SB numbers as most have a tendency to run a lot more than RL (in 2014 our WIS SB leaders were: 120, 119, 97, 86, 76, 65 - real life leader had 64).
It could be a normalization thing, but with all 2015 players that shouldn't have much, if any, affect.
