He pressured and tired out his opponents... Anyway, I can use different examples - Battling Nelson was a swarmer. Harry Greb was a swarmer. Jim Flynn was a swarmer.
Standing 5 ft 8 in (1.73 m) or 5 ft 9 in (1.75 m) tall, Sharkey was a standup brawler, who came right after his opponents. Sharkey was easy to hit, but rough and tumble and a hard puncher. He had unusually broad shoulders for a man of his height, and sported a tattoo of a star and battleship on his chest. He was a slugger who traded punches! Harry was swarmer you forgott Sam Langford!
Yes and yes. They were both throwing punches IN THEIR USUAL STYLES, just not landing the punches. Of course one can see how they move both feet and upper body....they weren't actors. Armstrong fought like Armstrong, Conn fought like Conn...they just pulled their punches.
