It's hard not to love that Penn State game. But, if I recall correctly, Nebraska was #1 and we were unranked, having lost to SUNJ the prior week. Hence, when you take down #1 in a program changing win, it outranks even PSU 87.
By contrast, while we hadn't beaten them since the earth was flat, at 5-0, ranked and at home, I'm not sure we expected to win, but we hoped and believed we could beat Penn State in 1987.
The same cant be said for NU 1984, which is why I think it gets the edge.
Fast forwarding to the present, whole some may argue over which Pinstripe Bowl win was best, I'll just put out there that Syracuse hasn't had its best win this decade ... yet.
