Why didn't Sugar Ray Leonard's brother Roger get his title shot against Ayub Kalue?

Answer 1

Roger Leonard - W 16 (KO's 7) TF 17 - W pct 94% - KO pct 42% - wins over J. Gant, C. Gray and M. Dennis (a fighter that I knew personally, he was managed by my cousin, former light wt champ, Joe Brown)

To answer your question, Roger was not good enough.
