The Minnesota Vikings are focused on upgrading at the QB spot this season. However, O'Connell gave Murray some praise for his understanding of the offense as the team prepares for its first preseason game Saturday against the New York Giants. “I think mentally he's definitely probably ahead of where I thought,” O'Connell said, per Kevin Seifert of ESPN.com. The likelihood is that the Vikings will play two of their three preseason games and then O'Connell will make the decision prior to the third and final game. O'Connell has said that he has a target date in mind for making the decision, but he has not revealed the date.
