"Pete Fierle, vice president of communications for the Hall of Fame, told ESPN that the Hall decides what will be in each display. He said the players don’t have a say in what will be placed in them." (Packers News)
Again, I have no doubt that the HOF makes the final decision regarding any exhibit. Fierle is not saying that there is a prohibition of players making any suggestions; just that the Hall makes the decisions. And Favre has been known to stretch the truth in other matters in the past, not the least of which was his retirement/unretirement game he played with the Packers (unsuccessfully) and Jets (successfully).
The Vikings jersey is a slap in the face to the Packers organization in my opinion.
