Mac and Newk above Connors and Lendl? No, that doesn't fly....certainly not in terms of accomplishments in singles.
If you are talking peak ability, sure, for one year Mac played like a God. But over the course of his career, not quite at the more consistent levels of Lendl and Connors, both with more weeks at #1, more titles and 1 more GS each.
