Many endorsement deals require the player to play a certain number of tournaments: for instance, I would assume that at least Head would want Agassi to continue to be active on the tour as well as Adidas. If the player is no longer visable then a fan (after a time) will not be influenced to invest in a player's gear. Agassi has made countless millions for products he has endorsed over the years, but whatever contracts he is under now will probably just eventually fizzle out as he removes himself from the lime-light. Though, I will venture a guess that he will be enticed by short term endorsement deals between now and the final of the US Open (which he will reach and de-throne Fed btw) and possibly shortly after the culmination of his career due to the attention tennis fans all over the world will be paying to one of the greatest to ever play the game. Companies will count on the seemingly endless nostalgia fans of any sport possess and will want to capitalize on such. However, I think as true tennis fans we should concentrate on the passing of sorts of an idol in Andre and should consider the man and not the endless barrage of subliminal (and not so subliminal) advertising we must endure as we celebrate his accomplisments as a player and philanthropist in the wake of his ever waning career. In closing, let me be the first to advocate one hell of a send off at the Open this year; one last hurrah for one of my heroes - here comes number nine.
