Even a dual meet would be brutally hard to predict and nearly impossible to stay impartial even as a neutral fan. I would obviously be more likely to favor 2001 or 2012 as I was not quite 7 in 1983 and didn't have near the access to watch them wrestle then.
Still here is my attempted exercise in futility.
125:Vega beats Mega by close decision and majors Riley. Megaludis beats Riley. Minn 4-0 over Iowa. Minn 3-0 over PSU. PSU 3-0 over Iowa.
133
avis majors Lawrence and techs Martellotti. Lawrence beats Mart. Minn 4-4 Iowa. Minn 7-0 over PSU. Iowa 5-3 over PSU.
141:True tossup but I give those to Iowa especially then. Kerber over Erikson. Both beat PSU by major. Iowa7-4Minn Minn11-0PSU Iowa 9-3PSU
149:Gotta give slight nod to a champ. Molinaro beats both in close matches. Lawrence beats Kistler. Iowa7-7Minn Minn11-3PSU Iowa 9-6PSU
157:Heffernan and Becker would be a great match. Alton is behind them. Give it to Heff. Iowa 10-7 Minn, Minn 14-3 PSU, Iowa 12-6 PSU
165:I have a hard time picking against Zalesky. Both he and Taylor major Pike. Iowa 14-7 Minn, Minn 14-7 PSU, Iowa 15-6 PSU
174:Ruth majors both. Volkmann beats Rico. Iowa 14-10 Minn, Minn 14-11 PSU, Iowa 15-10 PSU
184:A true 3 way tossup. You have as much luck drawing out of a hat, so I did! Iowa 17-10 Minn, Minn 17-11 PSU, Iowa 18-10 PSU
197:Banach by decision over Elzen and major over McIntosh. Elzen over McIntosh. Iowa 20-10 Minn, Minn 20-11 PSU, Iowa 22-10 PSU
285:Banach by decision over Lowney and pin over Wade. Lowney over Wade. Iowa 23-10 Minn, Minn 23-11 PSU, Iowa 25-10 PSU
Minnesota would have to win at 141,157 and 184 while still holding 125 and 149 and 174 to beat Iowa. Don't see it happening.
PSU would need Megaludis to beat Vega, Wright to beat Hahn and either Ruth to win by more than a major or Erikson to win by less than a major to beat Minnesota.
I don't see PSU beating Iowa even with best case scenario. Alton would have to beat Heffernan, Taylor beat Zalesky and Wright beat Goldman while Mega, Molinaro and Ruth would still have to win. Not likely.
