"A starter in four games last fall at left defensive end, Hagen made one other appearance in a reserve role and spent nine games on the inactive list. He moved from defense to offensive tackle late in the 1973 season and is ticketed for duty at offensive left tackle this fall.
Hagen came to the Bills in a trade with New England that also brought Jim Cheyunski and Mike Montler to Buffalo. A guard and defensive end for the Patriots, Halvor was a third round draft choice of the Dallas Cowboys in 1969 and was traded to New England in 1971.
Halvor attended Shoreline Community College for two years before moving to Weber State. He played defensive end for the Wildcats and was chosen for the Coaches All-America Game.
His hobbies are flying and skiing."
