When the Pinstripe Bowl matchup was announced, Pitt was an early favorite against Northwestern. Since then, the line has grown a bit making the Panthers bigger favorites.
The line opened at three points in Pitt's favor initially. As I wrote at the time, I expected Pitt to be favored by more than that. Well, since then, the line has grown to 4 1/2 to 5 points.
Part of the reason the line has to stay down a bit is that bowl games are just so fluky and you never know what you'll get. Still, I could see Pitt has solid six or seven-point favorites here.
