6 Degrees of separation

Jack Johnson to Charles Manson.

My clue is true grit on the beach

Best I can come up with for this:

Jack Johnson once fought Victor McLagen

who starred in numerous films with John Wayne

whose great-nephew/namesake Tommy Morrison

appeared in Rocky V, as did Sage Stallone

who also appeared in The Manson Family, playing one of the victims of Charles Manson.

Sugar Ray Robinson

John F. Kennedy

Sugar Ray Robinson

John F. Kennedy

John F. Kennedy is Edward Kennedy's older brother
Ali presented Edward Kennedy a pair of boxing gloves
Ali and Sugar Ray Robinson are connected in like a gazillion boxing documentaries.

John F. Kennedy is Edward Kennedy's older brother

I guess that would work too.

I was thinking of

Sugar Ray Robinson beat Henry Armstrong
Henry Armstrong beat Barney Ross
Barney Ross's friend Jack Ruby shot Lee Harvey Oswald
Lee Harvey Oswald killed John F.Kennedy

Jim Lampley to Paris Hilton:

Jim Lampley broadcasted with Manny Steward

Lennox went to a gay bar with Sol Campbell
Sol Campbell played with Wayne Rooney in the English soccer team.
Wayne Rooney was Ronaldo's teammate.
Cristiano Ronaldo had sex with Paris Hilton.

Good one, my way is:

Jack Dempsey was married to Estelle Taylor
Estelle Taylor starred in Don Juan with John Barrymore
John Barrymore was the paternal grandfather of Drew Barrymore
Who starred in ET

Rocky Marciano to Josef Mengele in 3 steps?

Good so far.
True Grit and Beach should take you over next couple of steps
That said your way works

The only way i can get around this is:

Jersey Joe fought Joey Maxim.

Joey Maxim fought SRR

SRR fought Jake LaMotta

Jake LaMotta was played in 'Raging Bull' by Robert DeNiro

Jake's brother Joey was played by Joe Pesci.

Good go.
My way was:

Jersey Joe Walcott beat Joe Baksi
Joe Baksi beat the actor Jack Palance
Jack Palance won an oscar in City Slickers a film that starred Billy Crystal
Billy Crystal co-starred in AnalyzeThis with Robert De Nero
Robert De Nero won an oscar for Raging Bull
Which also starred Joe Pesci.

Analyze that Oscar
