(Conference play only. Data from NCHChockey.com.)
So, on average, DU has scored 19.9 more goals per season of conference play than it has allowed, the best of any team in the NCHC, followed closely by SCSU and UND. Miami and CC have struggled mightily both in scoring and preventing goals, which is why they're both allowing about 30 more goals per season than they're scoring.
