Rathan-Mayes entered the 2017 draft out of Florida State University but was not selected. In three seasons at the school, he averaged 12.4 points per game while making 52.1% of his shots from the field.
After signing the combo guard, the Knicks have 15 players under contract. New York appears to be embarking on a genuine rebuild for the first time in over a decade, so it could mean the team will opt to keep young talent over borderline-rotation level veterans. If the Knicks go that route, Rathan-Mayes, who turned 23 in April, may have a decent chance to make the team.
