The NBA is planning on introducing more sleeved jerseys for the 2014-2015 season, including a sleeved version of the Portland Trail Blazers' "Rip City" alternate jersey as well as the Detroit Pistons' "Motor City" alternate, reports Chris Haynes of Comcast Sportsnet. The league is adding sleeved versions of teams' "heritage" jerseys.
The NBA has increased the number of sleeved jerseys teams have worn this season, most notably making their Christmas Day jerseys sleeved. 20 teams total are expected to wear a sleeved jersey at least once during the 2013-2014 season while five teams have added an alternate "sleeved" jersey into their uniform rotations.
More teams than not are open to adding sleeved jerseys into their wardrobes, but this next batch of sleeved jerseys is still "subject to change," according to Haynes. No other teams besides Portland and Detroit were mentioned, though "heritage" jerseys could mean multiple retro-themed sleeved jerseys are in the works.
