Athletes still do a pretty poor job in commercials in the 21st century. So as you can probably imagine, in the 1970s, they were terrible.

This Atari clip from 1978 featured baseball star Pete Rose, football legend Pelé and...Don Knotts. OK, so Don did just fine, but he was an actor, not a sportsman.
