The non-Ivy teams on this fall's football schedule have brought none of the mid-season breathing spells which the Crimson used to enjoy. First Buffalo jolted the varsity, 6 to 3, in the opener, and this afternoon an unbeaten Lehigh squad will bring into the Stadium one of the strongest passing attacks that Cambridge is likely to see this year.

Unfortunately for the Crimson, pass defense was the most glaring weakness in the Harvard ranks during last week's 21-14 loss at Cornell. The varsity backs simply don't seem to have the speed and experience needed to cover shifty receivers, and this fault, fatal against the Ithacans' Tom Skypeck, may again prove disastrous against lefthanded quarterback Bob Scheu of the Engineers.

Sophomore Scheu has performed impressively in the gap left by Lehigh's 1957 Little All-American quarterback Dan Nolan, completing ten of the 17 passes he has thrown. But a fair portion of his success must be credited to a brace of veteran ends--Joe Wenzel and Dave Nevil--who may well beleaguer the Crimson backfield all afternoon. Wenzell especially has the reputation of being one of the most deceptive and skillful receivers in the East.

Crimson coach John Yovicsin, attempting to bolster his offensive power, has made a major switch in the backfield. Sophomore quarterback Charlie Ravenel will start a game for the first time, a reward for the slickness and spirit he seemed to inject into the varsity attack in both the Cornell and Buffalo contests.

injuries, most notably at fullback where the depth chart trails off into an embarrassing nothingness after starter Sam Halaby. Second stringer Chris Hauge is sidelined with rib injuries, third stringer Jon Serbin will be out for the season with a fractured vertebra, and even Halaby is suffering from bruised ribs. In the emergency, halfback Glenn Haughie has been pressed into service as a fullback on a week's notice, but Yovicsin still winces at the situation.

The varsity should, however. have an advantage in the line. The Crimson wall, bulwarked by captain Bob Shaunessy, is one of the strongest lines Harvard has known in recent years and should be well coached to meet Lehigh's split-T offense, which Yovicsin had ample opportunity to study in his five years at Gettysburg, an annual Lehigh opponent
