I posted this in our league earlier. ynotjanns offense was overperforming for the first 50 or so games, as his team hit .280 while only having a .273 RL avg (this is w/o accounting for pitchers). The team had little power and no speed in terms of SB, and this is not surprising as he only spent 33M on offense. Most teams underperform RL average for reasons that are obvious: they face better hitting/pitching than a normal MLB team. Over the past 25 games, things started to even out due to law of large numbers and his offense started to slow down.
His last 3 games were shutouts and they can be easily explained. He was facing my team, at my home park of safeco, and faced my 11.8M Cy young 2x and my 12.4M Addie Joss, who both have sub 1 whip#. Throw together all these variables of elite pitching, extreme pitchers park, and a fairly underbudgetted offense, 3 shutoffs are not really that hard to believe.
