Why can't you change your team if you get another Arena Attempt?

So today while trying to get the rushing yards 5k yards achievement, I started arena but accidentally left my Kickoff HB off the team and had a spread captain by mistake so I'm stuck using spread plays.

Somewhat luckily, after one game I got a NTO ending the run, so I think "great, I'll just use 25 stamina and put my kickoff HB in" and put my WC captain in.

Nope, you're still stuck with the same team, same captain.

 WTF?

EDIT: I totally understand not being able to change after every match or even during the match, it makes it unfair, etc. But after your one attempt is cooked and you've lost, you should be able to change, especially since you're putting in your own stamina. Just my opinion.

I know right!! Even real NFL players can throw a hissy fit and change teams.

Haha, been burned by this a few times. I don't mind so much in arena, it's when I forget to switch before starting lvl drives.

Yup. It's been like that a while now. It would be nice for it to reset with the attempt but it doesn't. But we can't say we weren't warned it says that the lineup will lock in.
