Chappuis was also selected to play for coach Frank Leahy on the College All-Star squad against the Chicago Cardinals, who were the 1947 NFL Champions. In the 15th College All-Star vs. NFL Champion match, the Cardinals scored the biggest victory to date with a 28–0 victory. Among the collegians were Lujack and Chuck Conerly. The professional athletes included Paul Christman and Charley Trippi. Supposedly, the 1947 class had a void at fullback, which may have been the problem with their offense in the All-Star game shutout.
