The characterization of Rainsford, in Connell's short story "The Most Dangerous Game," is one which allow readers to see the stereotypical "man's man." Connell does a wonderful job providing both direct (blatantly describing) and indirect (based on the assumptions of the reader) characterizations of Rainsford.
Rainsford's agility can be inferred when he hears the gun shots echoing through the foggy night.
Rainsford sprang up and moved quickly to the rail, mystified. He strained his eyes in the direction from which the reports had come, but it was like trying to see through a blanket. He leaped upon the rail and balanced himself there.
It is through this description that a reader can assume (therefore indirect characterization) that Rainsford is agile and athletic.
Other descriptions of Rainsford are far more openly defined. When Rainsford is contemplating the gun shots, once on land, his intelligence is obvious.
"A twenty-two," he remarked. "That's odd. It must have been a fairly large animal too. The hunter had his nerve with him to tackle it with a light gun. It's clear that the brute put up a fight. I suppose the first three shots I heard was when the hunter flushed his quarry and wounded it. The last shot was when he trailed it here and finished it."
It is here that the reader comes to understand Rainsford's knowledge of hunting.
Over the course of the story, one cannot question Rainsford's quick wit, advanced intelligence, and physical stamina.
