Floyd Mayweather is the Anatoly Karpov of Boxing

Anatoly Karpov was world chess champion for ten years (1975-1985). Until the arrival of Gary Kasparov, he dominated tournaments and world title matches.

His style is described as "solidly positional, taking no risks but reacting mercilessly to any tiny errors made by his opponents." In his own words: "Let us say the game may be continued in two ways: one of them is a beautiful tactical blow that gives rise to variations that don't yield to precise calculation; the other is clear positional pressure that leads to an endgame with microscopic chances of victory... I would choose the latter without thinking twice." (Wikipedia)

Sounds familiar? It was only when Gary Kasparov came along that some excitement came back to chess. In the end Kasparov was beaten by a computer and could not stop the deteriorating interest in the game.
