It’s become an NBA cliché: As long as a player can shoot, he’ll always be able to find gainful employment somewhere. That coveted skill has helped many pros extend careers deep into their 30s, particularly as the league increasingly emphasizes the three-point shot. Three of the oldest players who competed in the NBA’s Orlando bubble – 40-year-old Jamal Crawford, 39-year-old Kyle Korver and 36-year-old JJ Redick – have not coincidentally combined to sink over 6,500 career treys, part of what makes them so valuable. On the opposite end of the career spectrum, on Nov. 18 many NBA franchises will hope to draft the next Korver or Redick, from a crop of prospects who with few exceptions are roughly half of Crawford’s age, having played only a season or two in college.
