Former NBA All-Star point guard Gilbert Arenas says Phoenix Suns shooting guard Devin Booker should be offended when he doesn't get double-teamed in pick-up games.

Booker and Joakim Noah got into it during a recent pick-up game after Noah told his team to double-team Booker. The Suns guard said you're not supposed to double-team on open-runs because players are trying to work on their games.

Gilbert Arenas took to Instagram to give Devin Booker some advice from one scorer to another:

Devin Booker has established himself as one of the best scorers in the NBA. However, it's clear Arenas wants Booker to embrace the double-team and develop that assassins mentality.

Booker was just frustrated because he was solely trying to work on his offensive game, but playing out of double-teams is part of basketball at the end of the day. All the great scorers in NBA history had to learn how to play through double-teams, and Booker has to experience it sooner or later anyway.

Last season for the Suns, Devin Booker averaged 26.6 points while shooting 46.7 percent from the field, 32.6 percent from beyond the arc and 86.6 percent from the free-throw line. The sky is the limit for Booker, who is only 22.
