Although Champion began producing jerseys for all NBA teams for the 1990-1991 season, they didn’t start producing replica jerseys for resale until 1991-1992 (most likely the summer of 1991, prior to the start of the season). Evidence of this can be seen in the Portland Trailblazers jersey design. For the 1990-1991 season, the Trailblazers had the “lower case” Blazers logo. No Champion Trailblazers replica jerseys exist with the older “lower case” Blazers logo from the 1990-1991 season.
For the 1991-1992 season, the Trailblazers updated their logo to the “upper case” Blazers logo. All Champion Trailblazers replica jerseys have this logo. However, the heat-transfer/screen-printing techniques that Champion used during the 1991-1992 production run were primitive. In fact, it appears that Champion rushed jerseys to market. A lot of the initial replicas from the 1991-1992 season were very basic and lacked the detail of the jerseys that teams actually wore on the court. For instance, the Trailblazers didn’t even have their signature stripes (blaze) on the 1991-1992 replicas jerseys:
Much of this was probably due to the limited platen size available on the heat presses that Champion was using in their production facilities. The platen is the heated upper plate on the heat press and most likely was 14″ x 14″, which means that printing outside of this size range wasn’t possible. Therefore, all designs would be limited to a 14×14 area on the jersey. Therefore, while the authentic Trailblazers jerseys had stripes that run across the entire front torso, the replica jerseys initially had stripes that were short and limited to the width of the “Blazers” logo. Champion would add the stripes to the Trailblazer replica jerseys for the 1992-1993 season.
In addition to adding the stripes for the 1992-1993 season, Champion also changed the neckline from a multicolor white/red trim, to a solid red trim. They also released white home jerseys, although they were extremely limited in both player availability and quantities printed. It was common for Champion to mainly release road jerseys for most teams, while home jerseys were limited and harder to find.
Champion wouldn’t change the Trailblazers jerseys until 1998-1999. It appears during this time that they finally were able to update their printing techniques and print across the entire front torso of jerseys (for instance, other teams like the Utah Jazz finally had logos that stretched across the entire chest). The stripes stretched across the entire torso, replicating what the players actually wore on the court. The only other change was the players names on the back of the jerseys went from straight orientation to a rounded/curved orientation. Also, Champion issued more white home jerseys in a wider variety of players, although quantities were still limited, and they are still scarcer than the black road versions.
While most teams eventually transitioned to vests by the 2000-2001 season, the Trailblazers were one of the few teams that still had the traditional tank-top style jerseys when Champion ceased production of replica jerseys after the 2001-2002 season.
