2. Inability to shoot from long-range
Although Daryl Morey has speared the Philadelphia 76ers, they've been far from a Daryl Morey team on the court. Morey has always put together 3-point shooting teams, as his Houston Rockets teams largely changed the game of basketball (in addition to the Golden State Warriors) by launching (and making) an avalanche of long-range shots.
The best Rockets teams ranked first in 3-pointers made (2014-15, 2016-17, 2017-18, 2018-19, 2019-20), and always had a legitimate corner 3-point shooter, which was usually PJ Tucker. The 2023-24 Sixers rank 28th in made threes, compared to their 12th rank just last season.
The Sixers also rank 23rd in 3-point percentage, which is a meteoric drop-off from their league-leading 38.7 percent in 2022-23. Part of the issue is roster construction, as the Sixers lack long-range snipers and playmakers alike.
Being able to shoot from deep means you're never out of a game, because you can always shoot your way back into the game. It also can allow you to get to an insurmountable lead and close out an opponent early on.
Not being able to do that could be the death of the Sixers.
