(Corvallis, OR)  --  Oregon State head coach Gary Andersen says he hasn't decided who will start at quarterback this evening against Weber State in the season opener for both teams.  It will be between redshirt freshman Marcus McMaryion and true freshman Seth Collins, who execute the Beavers' two-quarterback system.  It will be the first game as OSU's head coach for Andersen, who replaces longtime coach Mike Riley, who's now at Nebraska.  Kickoff is set for five p.m.
