Was Tommy Hearns "green" when he fought Leonard for the first time?

Every fighter has an Achilles heel.
Hearns was his legs. It was noticeable
against Leonard as early as the 6th rd
in their 1st fight.
As early as the very 1st rd against
Hagler, his legs were buckling.
The issue popped up against Roldan
and Barkley were he was very unsteady
on his feet when pressured.
The problem was 95% of the boxers
in history, especially at welterweight
couldn't exploit that weakness.
His offensive skills, overwhelming
combination of height ,reach, speed,
and power, made it an almost
impossible task for all but the
very best fighters in history at welterweight
Jr.Middlweight.
And a great many middleweights and
Lt. heavys.
I don't believe it was lack of experience
against Leonard, but the 1st time we
saw a chink in his armor .
