Among the excellent examples give are the excellent welterweights Buddy McGirt and Pernell Whitaker who although (both) short for their weight classes did not (automatically) become inside fighters.
On the other hand, Pernell was also trained by George Benton, whom was also a great defensive fighter in his day.
