With 12 assists in a single game, have the Mavericks found a qualified backup point guard?

In a previous NBA preseason game, the Dallas Mavericks defeated the Utah Jazz at home 114-101. After this game, the Mavericks' record in the preseason improved to 2 wins and 1 loss, while the Jazz suffered a three-game losing streak during the preseason and currently have a record of 0 wins and 3 losses.

In this game, the performance of the Mavericks' substitute backcourt rookie Ryan Nembhard was impressive. Nembhard played 26 minutes and 24 seconds, making 2 of 6 shots, 1 of 4 from beyond the three-point line, and 1 of 2 free throws. He scored 6 points, 5 rebounds, 12 assists, and 1 steal. He also had 1 turnover and 4 fouls, with a plus-minus of +14. Although Nembhard had a mediocre touch on the offensive end and did not score more points, his performance in passing and organizing offense was phenomenal. He constantly sent passes to his teammates, and the team's offense seemed orderly under his organization. In addition, Nembhard's performance on the defensive end is quite satisfactory, and he can also play a certain role. Overall, Nembhard has displayed his own characteristics on both offense and defense. The team's situation is also very good when he is on the court. His series of outstanding performances are also an important factor in the team's ability to defeat opponents.

Nemhard was born in March 2003. He is 22 years old and was the undrafted pick in this year's NBA draft. However, the Mavericks offered him a two-way contract after the draft, and they still highly recognized his abilities. According to the data from the previous joint trial physical test session, Nembhard's barefoot height is 180.3cm, his wingspan is 188.6cm, his standing reach is 238.8cm, and his weight is 79.7kg. In the NCAA last season, Nembhard played 35 times on behalf of Gonzaga University, averaging 35.1 minutes per game. He averaged 10.5 points, 3 rebounds, 9.8 assists, 1.7 steals and 0.1 blocks per game. He also had 2.5 turnovers and 1.6 fouls. He shot 44.6% from the field, 40.4% from the three-point range, and 77% from the free throw line. In the previous NBA Summer League, Nembhard played a total of 3 times, averaging 29.5 minutes per game, averaging 11.3 points, 2.7 rebounds, 6.7 assists and 0.7 steals per game, as well as 3.7 turnovers and 3.7 fouls. He shot 40.6% from the field, 33.3% from the three-point range, and 83.3% from the free throw line.

So far in the preseason, Nembhard has averaged 17.3 minutes per game in the first three games, averaging 5 points, 3 rebounds, 5.3 assists, 1 steal, 0.7 blocks, 0.7 turnovers and 1.7 fouls. He shot 40% from the field, 33.3% from the three-point range, and 50% from the free throw line. Nembhard didn't play too much in the previous two games, and his performance couldn't be considered particularly outstanding. He got more playing time and ball rights in this game, and his performance also improved significantly under this situation. Although he is only an undrafted player, does Nembhard have a chance to establish himself in the Mavericks who lack a point guard?
