I don't think you paid attention last year. The conference as a whole has been playing a much more difficult non-conf. schedule.
Stevens was 14-5 non-conference last year, beating then #2 Cortland, #20 Kean, #25 William Paterson and #35 Western New England. Three of their five losses came to ranked teams, as well (Salisbury, Eastern CT and TCNJ). This year they have 8 games against top 25 teams, as well, and they also play a DH against RIT.
However, I guess they agree the Skyline is a weak league overall, as they're heading to the Empire 8 in '08.
