Andrew Luck is not expected to take classes next quarter at Stanford, according to two people close to the NFL prospect. Luck is expected to declare and focus on preparing for the 2012 NFL draft, in which he is expected to be the No. 1 overall pick. That move counters speculation by some that Luck would possibly return to Stanford for another season or at least threaten to manipulate who will take him in the NFL draft. Luck is a senior, but redshirted as a freshman in 2008, giving him the option to play one more season.
