It seems that the feed at ical.mac.com hasn’t been updated yet for this years schedule and one game has already been played (and won by Detroit, I might add!). So I went looking for a new feed provider… and found Yahoo. My Upcoming Events plugin seemed perfectly capable of handling the Yahoo feed. So now, simply by putting http://sports.yahoo.com/nfl/teams/det/ical.ics in the Path field and clicking the “Update Now” button in the Upcoming Events options, I was able to get the upcoming Lion’s games back into my calendar.
