The Wisconsin Badgers were represented in 1970 by Rick Reichardt. He later wore the candy striper uniform with the White Sox.
Jim Sundberg was the only Iowa Hawkeye to be included in a Kellogg's set. He appeared in 1979 and 1983. Harry Caray had a challenge with names and he really had a challenge in the late 1980s when the Cubs had Sundberg, Scott Sanderson and Ryne Sandberg.
The University of Illinois was represented by Tom Haller in 1970 and Ken Holtzman in 1974. I remember fighting through huge crowds at Wrigely after a game and getting his autograph not once, but three times!. It was a disappointing day when Holtzman was traded to the A's for Rick Monday.
Steve Garvey and Kirk Gibson both attended Michigan State. Garvey showed up in six sets (1975 - 1977 and 1980 - 1982) and Gibson was included in the 1982 set.
Dave Winfield and Paul Molitor went to the University of Minnesota. Like Garvey, Winfield appeared six times (1977, 1978, 1980 - 1983). Molitor showed up in the 1979 and 1981 sets.
The University of Michigan was represented by three players. Bill Freehan (1970 and 1972), Elliott Maddox (1975) and Geoff Zahn (1979) all found their way into a set. Zahn spent a few years with the Cubs before getting good enough to be in a Kellogg's set.
George Sisler is an honorable mention here for Michigan. He did attend Michigan, but the school didn't play in the Big Ten during his time at the school. Plus, Sisler wasn't an active player during the 1970 - 1983 run of Kellogg's cards. Sisler appeared in the 1972 All-Time Greats set.
