Source: Favre the cause of "jism" in Vikings’ media room

What two knowledgeable NFL people described earlier this week as a "substance" in the Minnesota Vikings mediaroom was described today by a third informed person as "jism."Sources with knowledge of the Vikings media room dynamics say some reporters believe the jism was secreted by media members who are still enamored with Vikings quarterback Brett Favre. While no media members would go on record about the source of the jism, they did say it will only increase if the quarterback plays well.
