Also was thinking about Career Ending Injuries or other Career Enders.

1. Career Ending Injuries
like have a injury like Michael Irvin , Steve Young , etc. in their career and it could happen in the beginning of their career , middle of their career or even near the last part of their career.

2. Other Career Enders
Like have a player retire because he thinks he rather play basketball , baseball , hockey or any other sport than football , like he didn't like his draft pick so he rather retire and do something else that is not a Sport , like he doesn't want to play in the NFL but he rather play in the CFL , etc.

For the love of god no, it's hard enough to build and put together a roster and deal with the draft with the randomness of boons and busts. Just randomly losing a player for good, especially one of your stars to RNG? Yeah......

I'm going to give this a big -1

Would you go for this if the ROSTERs were expanded??

If not what would have to happen for you to say YES to this?

-1

Roster expansions would mean more players to draft/sign and even more work to deal with. Plus random career-ending injuries to key players would just be too much. Realistic? Yes. Needed? No.

There really isn't anything I can think of that would make this a good idea in my mind. There is already enough RNG in the game when it comes to drafting, player development and injuries. Lets say you're a team that wins regularly and picks towards the bottom of the draft. You just gave up 3 first rounders to move up and get a top notch HB that your offense relies on to run it's scheme. Now 4 games in he gets a career ending injury and your team now has nothing to show for everything it just gave up. No thanks.

can't tell you how many times thats happened :(

I believe a serious injury increases the chance of retirement. I've had a few talented guys retire early on me.

Or because he meets Robin Givens.
