Removing Players Nametag

Is it possible to remove a players nametag without putting an entity on him? If so can someone point me in the right direction of doing it, it doesn't matter if it uses NMS ? Thanks.

(The reason I don't to put an entity on his head is because they wont be able to teleport for some reason, you could also help me solve that if their is no other way )

 

I just came off my computer >.> thanks if this works xD

 

It still shows the nametag,

debug code:

Code (Text):

    @EventHandler
    public void onJoin(PlayerJoinEvent event) {
        refreshNameTag(event.getPlayer());
        teams.addPlayer(event.getPlayer());
        System.out.println(teams.getNameTagVisibility());
        if (teams.getPlayers().contains(event.getPlayer())) {
            System.out.println("team contains player!");
        }
    }

Outcome in console:

Any other solutions?

@avighnash do you need the full code if you think im doing something wrong?

Edit: BTW refresh nametag has nothing to do with the team

 

1.9.x >.>

 

Back on phone- will try this in the morning

 

Omg... I didn't set the players scoreboard lol, I just added him to the team, ty
