Actors who should have played boxers

[Brutu]

You ever see a movie biography about a famous fighter and the actor who plays them looks more like a weenie?
What actors should have played famous fighters?
my pick Fred Ward(Remo Williams) should have played Oscar"Ringo"Bonavena.
except he probably too old too now, Bonavena was 33 years old when he was killed.

How about Gael García Bernal as the young Duran and Luiz Guzman as the old Duran.
