3. Not signing Kelly Oubre Jr.
This reason goes together with the Dallas Mavericks choosing to re-sign Markieff Morris, as there was a much better option on the market and his name is Kelly Oubre Jr.
Oubre Jr. is someone who was available when Dallas signed Morris and Dallas also reportedly showed interest in him this summer.
Although Oubre Jr. has been sidelined as of late due to an injury that he suffered when he was hit by a car, he has proved that the notion of him putting up empty numbers for bad teams is false.
The 76ers are sitting at 12-7 and Oubre Jr. was putting on a show during the time he was healthy. Oubre Jr. is averaging 16.3 points, 5.1 rebounds, and 1.4 steals per game while shooting 37.8 percent from downtown. He remains a lethal scorer and could have given Dallas another wing to throw into the mix.
Oubre Jr. may not have solved the defensive issues that Dallas has, but his offensive firepower is enough to show that Dallas could have made a mistake by not signing him. They could have gotten him for cheap and he would have been able to provide a much bigger impact than Markieff Morris has.
Oubre Jr. signed a veteran's minimum with Philly, but his play this year could lead him to landing a bigger contract next summer.
