STANFORD, Calif. — About the only thing that went wrong on national signing for Stanford was having to replace the toner on the fax machine.

Once it started working, the ink sure looked good.

Stanford sealed one of the best recruiting classes in school history Wednesday, signing three of the nation's best offensive linemen to letters of intent to block for the son of Hall of Fame running back Barry Sanders. The academics-first university rolled up rankings in the top 10 of several recruiting services — believed to be a first for the program.

Five-star linemen Andrus Peat, Kyle Murphy and Joshua Garnett all committed to the Cardinal, which is losing projected high first-round NFL picks in tackle Jonathan Martin and guard David DeCastro — not to mention quarterback Andrew Luck.
