Agassi explains that he had a congenital lumbar spine defect that affected his mobility as he got older, which can clearly be seen. It seems to me that Agassi was hitting the ball better than ever in the late 90's, early 2000's, but, his mobility decline offset that. He compensated well by standing in close and cutting off angles. But, against players like Sampras and Federer, Agassi's lack of world class mobility was exposed.
PS: I would also say that Agassi's peak level of play might have been higher than Lendl, McEnroe or Connors. But, it was too sporatic, and not sufficiently sustained, to give him full credit for that. Compare Borg, whose career was short, but, it was virtually all peak with a ridiculous winning percentage, especially at the majors with 11 titles out of 27 attempts.
But Limpin, Agassi never had one year in which he won 90% of his matches. Lendl, McEnroe and Connors AVERAGED winning over 90% of their matches over five years. That's true dominance.
And I do think for one match a guy like McEnroe's best was superior to Andre's best. Agassi had super duper groundies but his movement wasn't that good compared to other greats. He looks flashy when he hits those fantastic winners of his off service return but he also got aced more than some other great returners and a number of players like Murray would tie him for percentage of return games won. Some had higher percentages of return games won lifetime.
But I'll give you the chance that Agassi's best MAY (maybe not also) be better for one match than the ones you mentioned.
