When Harvard football team can up only eight first downs and handily over an Ivy League there arises the vague that the defense has been doing heavy work.

of Harvard's three touchdowns Columbia were set up by the inside linebacker Bob Barrett a punt at the Lion six-yard line, and Ken Boyda recovered a Columbia at the 22-yard line. The offense's consistency has been in capitalizing the opportunities presented by the .

The Crimson front wall has effectively the running attacks of its three but the pass defense, though seriously pressed, has shown signs weakness up the middle.

of the defensive secondary's is that the defensive line plays a pursuing rather than charging type of game in order to gear against opponent's running game. This means that the opposing backs will have a harder time picking holes in the Crimson line, but that the quarterback will have more leisure to release his passes.

Harvard's only pass-rushing threat against Columbia came in the form of tackle Dave Davis and an occasional blitz by the inside linebackers.

The Crimson cornerbacks, Bob Norton and Bill Cobb, are becoming solid defenders against sideline patterns, and safetymen Dave Poe and John Dockery very effectively employ a zone type of coverage on deep passes. It's up the middle, where receivers can hook in behind the interior linebackers, that presents a problem.

Columbia kept the Harvard interior linebackers off-balance by alternating with running and passing plays. When the Lions started gaining healthy chunks on the ground, Crimson linebackers Barrett and Jim Driscoll tightened up to the line, and Columbia started throwing passes up the center.

The linebackers will always have to give away something, hopefully the opponent's weakest point.

Against Cornell this Saturday, Driscoll and Barrett may tighten up a little to stop the Big Red running game. Fullback Bill Wilson, last year's leading ground gainer for Cornell, and halfbacks Pete Larson and Ron Genvase present a formidable attack. Larson and Genvase have combined for 455 yards in three games, averaging over seven yards a carry.

Cornell may have to depend on its running game more than ever if quarterback. Marty Sponaugie does not return from the injury list. When Driscoll and Barrett close in to throttle the Cornell runners, don't be surprised to see Cornell pounding the middle with passes.
