Kevin Durant is known for firing back at his critics via social media, and the newest member of the Houston Rockets did just that after hearing what a former NFL player said about him on Monday.

Emmanuel Acho, a former NFL linebacker who is now an analyst for FS1, said on Monday’s edition of “The Facility” that he has developed his own formula for measuring a player’s legacy. Acho believes you should take the number of championships a player has won and divide that by the number of teams said player has played for. A higher number means a better legacy.

Acho used active players Stephen Curry, LeBron James and Durant while explaining his formula. He said Curry has the best legacy of the three since the Golden State Warriors star has won four titles while playing for only one team. LeBron has won four titles but played for three different teams, so Acho gives him a score of 1.3. Durant, who has won two championships but just joined his fifth team, has an Acho “legacy” score of 0.4.
