On March 25, 2013, the Ottawa Senators signed undrafted free agent Charles Robinson III to an entry-level contract. The move caused little commotion at the time. He played six regular season games down the stretch with Binghamton, recording four points in that span. However, it was in training camp that first off-season that he made a big impression, and the legend of Buddy Robinson was born.
Robinson signed his ELC after playing two years of college, and then immediately left college to turn pro. His first full season with the Binghamton Senators was impressive, in which he notched 31 points in 69 games.
