Isaiah Joe fits the profile of the 76ers’ prototypical reserve. The third-year guard is an accomplished three-point shooter and a solid defender. However, Joe couldn’t stay in the Sixers’ rotation this past regular season. He followed that up by playing a total of 1 minute, 8 seconds in the final four games of the second-round playoff loss to the Miami Heat. Even that’s a bit misleading, considering those minutes came in mop-up duty in the series-ending Game 6. The problem was Joe didn’t always flourish when called up.
