If you insert that content again, you'll be blocked. Mr. Darcy talk  
One solid example of why that content can not stay. Your edit said: The story was unsubstantiated, with no presentation made of either tangible proof or any named sources. Yet the reference you provided to back that up is an article by Glazer himself that says: Several sources have told FOX Sports that Favre earlier this year phoned the Detroit Lions prior to their battle versus Favre's old team, the Green Bay Packers, and gave them a rundown of the nuances of what Green Bay does on offense. According to the sources, Favre actually spent over an hour on the phone with Lions coaches, who were connected with Favre by then-team president Matt Millen. That story is not "unsubstantiated" and the use of anonymous sources is completely normal and accepted in journalism. Calling the story unsubstantiated is a violation of WP:BLP, and implying that it was incorrect because of the lack of "named sources" is an arbitrary standard that violates WP:NPOV. In addition, in the third source you provide, Favre admits that he did have a conversation with the Detroit executive, and that "Favre said former players and coaches exchange information all the time." That doesn't disprove anything Glazer said, and in some ways seems to support it. As I said above, if you reinsert that content, I will have to block you from editing. Let's not get to that point; find new reliable sources and quote them properly, or leave the article alone. Mr. Darcy talk 

The story is unsubstantiated.  There is no other than Jay Glazer who has said that this has occurred.  Favre himself tells a completely different story.  Glazer's story becomes nothing more than a "He said, he said" without anyone else backin it.

The fact that you would threaten to block my ability to edit is ludicrous.  You are not an administrator here.  If you change my information, should I threaten to have you blocked, as well?  How about this:  If you have me blocked from editing, I shall request that the same occur to you.
