I'm not convinced that it's okay to just remove all the dome-teams from the plot. Using the author's data, here's a plot of all the teams and total fumbles (not 'fumbles lost' that the author focuses on): http://i.imgur.com/QP6LXWg.png http://i.imgur.com/QP6LXWg.png The Patriots are not even the top team! It's actually the Falcons that have the most plays per fumble. If it's "nearly impossible" for the Patriots, what does that say about the Falcons? The author focuses on "fumbles lost" because that number is more dramatic if one is trying to prove that the Patriots did something wrong. That number in isolation only shows that the Patriots were extremely good at recovering their own fumbles. Looking at the graph, there is a notable bend at the top 4 teams. Either the top 4 teams have fewer fumbles through training, or the top 4 teams are all cheating somehow. It's hard to call the Patriots statistics impossible when they're in 2nd place.
