That '93 PSU team had all the pieces but it just wasn't ready to contend. Kerry Collins, most of the O-line, running backs and Brady in their first year as starters.
They really lacked firepower at wideout. Engram improved and ended the year a B10 caliber receiver but Scott was still figuring it out and only had 12 catches on the year. (LaBarca was actually the 2nd in catches from the wideout position).
Given inexperience at QB and the question mark at wideout, you could compare '93 to the 2023 team. But this team is in much better shape defensively, the O-line is more experienced and the running backs are already at all-B1G level and only going to get better.
I think the '93 Michigan game, in hindsight, was notable in that it was the game where the B1G officials basically served notice of who they were really working for. All pretense of objectivity went out the window in that game.
B1G zebras actually met with MIchigan during the week and strategized about how to deal with the crowd noise at Beaver Stadium. They and the Michigan coaches came up with a plan and they practiced it. You see that Todd Collins knows exactly what to do and looks at the officials, who then started calling penalties on the Penn State fans (which is the only time that ever happened).
Paterno and the PSU coaches were completely blindsided -- I doubt they expected that the B1G officials would be so transparently trying to nullify the home field advantage and help Michigan win the game, but there it was. It didn't win the game for Michigan but we know a crowd can be worth 7 points, and it definitely shook PSU psychologically. I don't think it excuses the loss. PSU had better personnel that day and should have beaten Michigan, and that's on Paterno and Fran Ganter.
