In the varied business and social environments I inhabited I never once observed name calling, praise or degradation of physical characteristics or criticism of anything other than a business decision and this too with immense care and respect.
So I think it's the one that is easiest to anticipate and see off in the distance because the funny thing is that Henry Aaron never got this kind of glowing praise when he was playing, and not even 10 years after he retired.
He has always been generous in his praise of Sampras, who never won at Roland Garros but triumphed twice at the Australian Open and holds the record for winning eight successive Grand Slam finals.
