A 2015 graduate of the highly-regarded Virginia Commonwealth program coached by Shaka Smart that captured the attention of basketball fans across North America with its electrifying style of play and NCAA tournament runs, Weber’s professional career started slowly after he tore both his ACL and MCL midway through his final season with the Rams. He began his first professional season with Sioux Falls, the NBA G League affiliate of the Miami Heat, and earned contracts to play six games (earning four starting assignments) with the Memphis Grizzlies and one with the Heat later in the year.

In his second professional season with Sioux Falls, 2016-17, Weber was selected to the NBA G League All-Star team and was voted to the All-NBA G League Second Team at the end of the season. During the year he appeared in seven games with the Golden State Warriors and 13 with the Charlotte Hornets after signing 10-day contracts with those clubs.

After being one of the final cuts by the Los Angeles Lakers during their 2017 training camp, Weber signed a two-way contract with the Houston Rockets. He saw action in 13 games with the Rockets during the 2017-18 season while splitting time between Houston and its G League affiliate in Rio Grande Valley. He finished that season with Sioux Falls and with the Memphis Grizzlies.
