We’ll be seeing even more sleeved NBA jerseys next season. According to CSNNW, all “heritage” shirts in 2014-15 will feature the sleeves:

In the case of the Portland Trail Blazers, their popular white “Rip City” jersey will be converted to a short sleeve fit. The same goes for the Detroit Pistons and their blue “Motor City” jersey.

There’s reluctance by some teams to switch up their look, we’re told. However, this is something the league wants to occur and there’s more teams in favor of the change oppose to the ones that are not, another source said.
