It was a tough call as to who was more a jerk, Mac was the entitled spoiled brat , whereas Connors was the veteran asshole who never did grow up.
Always thought Ivan Lendl got a somewhat raw deal because the American media wasn't thrilled with him consistently besting Mac and Jimbo, once he got stronger, both physically and mentally.
However Connors got a late career resurgence to beat Lendl in back to back USO, whereas once Lendl overtook Mac he never looked back.
