Long before you called yourself Muhammad Ali
you floated like a butterfly stung like a bee.
Your right must have really felt like a piston
in the famous fight against Sonny Liston.
Cassius Clay became a name of the past
yet the title you fought for may somehow last
So, will you take one last ride on your boulevard
in memory of the punches that hit so hard?
I have been amiss not to have commented here when I read it the day you posted.
Your rhymes always give a timeless value to your work. (Boulevard matches the cadence of hit so hard; piston & Liston). You are fearless is using this style. It is not enough to make the rhymes, you endow them with the power of driving pistons and punches.
One typo: 2nd line you have "life" - I think auto spell substituted it for "like"
