I haven't fully dug into it, but the article may not be apples to apples. The comparison uses the NL team that we and others play during the week of interleague...the Rockies this week for us. I looked at the schedule and found 4/16 teams play 18 inter league games (Reds, Dbacks, Mets and Marlins), the rest play 15. However that doesn't mean we play an entire extra series against the Rockies...both the Reds and Brewers play them 7 times. It's likely 3 extra games spread across 3 teams. I haven't dug into it, but that would be the proper compare to see who has the overall tougher schedule.
