What was billed as a two-headed monster didn't seem very heady at all.
Princeton's senior quarterback tandem of Greg Mroz and Bill Foran looked like it might threaten a Penn defense reeling from an encounter with Brown's nation-leading passer Michael Dougherty.
The reality was anything but. Fewer than 20 minutes in, Mroz was out for the game with an interception and a concussion, leaving only Foran's run-happy attack.
"We'll never know if [Mroz] were in the game, if we would have played better or worse," Princeton coach Roger Hughes said.
It's hard to imagine that it would have been the latter.
Sporting a 4.5-second 40-yard dash, the senior was nonetheless ineffective. Usually, Foran is good for around 5-7 yards a carry. Saturday, he finished with a net of 39 yards rushing on 13 carries - a figure dragged down by Penn's three sacks.
"Last year their [offensive line] was a little slimmer," said Penn senior nose guard Naheem Harris, taking the Quakers' first shutout in over a year as an opportunity to make a rare press conference appearance. "I don't think they were able to move as well as they did last year."
Most importantly for Penn, Foran managed only two runs of more than eight yards, and both of them started from Princeton territory.
Harris and his front seven had plenty to do with that.
The nimbler Foran eluded Penn's 285-pound senior more than once, but Foran was generally kept in check and in the pocket.
Those big runs of 27 and 24 yards were anomalies; more often, Foran found himself stepping up into a quickly-collapsing pocket for only a short gain.
"This is not the first time we've played this [type of] offense," Harris said. "We were able to get to the wide side of the field before he had a chance to use a lot of his speed."
"I really don't know that schematically [Penn] did anything we hadn't seen in the past," Hughes said. "We weren't blocking the linebackers we were supposed to be blocking."
Hughes has gotten used to inconsistent production from his offense, and more specifically from his quarterbacks, since the graduation of Jeff Terrell.
But with his top two receivers injured and his running backs stuck in neutral, he needed Foran's legs on Saturday as much as ever.
Penn shut them down, though, and Foran's passing numbers suffered as well; 13-of-27 (Princeton is last in the league in completion percentage), 91 yards, zero touchdowns.
And for the first time since 2004, no win over Penn.
