Alright, here's a mock-up for switch. I chose a different type of "switch" as I think it lends better to the idea and there won't be any confusion on whether it's being turned on or off.
I have not messed with sizes yet, but I think I'd be able to get this to work. I might mess around with the border because I'm not 100% liking it, but you get the general idea.
Also, keep in mind that "regular season" and "playoffs" may have to be the only words due to size. So, remember that when you're picking avys. For example, the Mez one previously had him in the Tampa uni, so that might not work.
If you noticed, the "regular season" panel has all the colors muted - as if it were a flashback or something.
Edit: I'm open to timing suggestions. Also, I think when I get actual players in there, it'll look better. I'll do another.
