AFL Uniforms Collection Question.

I've been out of the loop on this game for about a month but decided to come back to do some collections and start up a team again..I have completed all of the uniform collections and the leg stadium collections, and am wondering how you get the Broncos Away, Chargers Home, Chiefs Away, Jets Home, Raiders Home and Away, and the Titans Home. Maybe one or two of these were from the beginning collections that I may have deleted, but the rest are ones I haven't seen before..thanks for any insight.|||I'm confused too, man. I'm not sure if they're just pulled or what.|||ult. packs|||u get those from packs.
