it's always been a myth that Wilson played a bunch of cold-weather games at Wisconsin.
You can find the game temperatures here:

In home games:
1. vs. UNLV: 90 degrees.
2. vs. Oregon State: 71 degrees.
3. vs. North Illinois: 65 degrees.
4. vs. South Dakota: 60 degrees.
5. vs. Nebraska: 50 degrees.
6. vs. Indiana: 52 degrees.

It doesn't look like any of his road games that year had particularly severe weather either.
