Sugar Ray Robinson

Boxing is not a perfect game of any sort:

The celebrity can be off-putting.
The racism talk, from Johnson-Jefferies
To Mayweather-MacGregor, for marketing, is disgusting.
Seedy promotors and hangers-on
Can take away from the art of it.

And the before and after photos:
Of body jabs, kidney shots,
Swollen heads, and the sour taste of blood,
Is not an easy sight on the eyes,
If they have not already been swelled up.

But this science can indeed be sweet
Whenever he steps into the ring.
