How do you get jerseys

I’m new to this madden and I was playing online I seen someone had 75th anniversary eagles blue and gold jersey or the Kelly green ones how can I get these??

Go to the season points shop at the very end and there should be uniform packs from the different seasons. Pretty sure that Eagles one you want is from season 2

There’s an option in the store for tickets (135 I think) that provides a variety of alternate uniforms.

There is also a field pass reward every season. Also, playing the Nike rivalry solos will get you some more as well. Though I don't think there are Eagles Nike jerseys.
