San Diego Chargers director of pro scouting Fran Foley has agreed in principle to become the new director of player personnel for the Minnesota Vikings, and a deal is expected to be completed by the end of the week. Foley would become the third "point" in what new Vikings owner Zygi Wilf has described as a "triangle of authority" in the franchise's revamped football operation. In the front office model described by Wilf last week, vice president of football operations Rob Brzezinski and the club's personnel director will work with new head coach Brad Childress in a committee approach. The highly respected Brzezinski signed a three-year contract extension during the final weekend of the regular season. Childress, former offensive coordinator for the Eagles, was hired two weeks ago to replace the deposed Mike Tice. Wilf has been clear for some time about the need to hire a top personnel executive. After the Vikings interviewed at least seven candidates, Foley was offered the job earlier this week. The two sides are working toward finalizing his contract.
