Sure I want the ratings to matter, but I also want some semblance of football realism. O linemen rarely, if ever, sub out of the game unless it's a package sub or injury issue. I could deal with it if it was just one low stamina guy subbing out on longer drives, but not half the line and guys with good stamina relative to the rest of their peers at their position in the league.
I most definitely do not want my starters disappearing altogether late in the game.
I have started a new CFM with the Rondo rosters and this solves all of these issues in addition to seeing a good rotation at RB. Yes, over time this will slowly erode as new rookies come in. Then you are merely back to default auto subs which is what a lot if folks play on anyway due to the fact that the system is broken and left for dead by EA.
But hey, to each their own.....
