How do I stop...
 

How do I stop the game from inserting other o-lineman during the game?

I sent my depth chart and lock the players. I keep all my o-lineman at 100% play time and locked, but when I sim the game I see back-up lineman playing also. Now keep in mind I set everything in my control in global editor. It's really a pain with this. Now, i know the NFL aren't subing lineman on a drive, so why is this game doing this?

Any help with this matter.

Endurance, I would think.

Your guys are just getting tired and need a breather. To make sure, check out you starters endurance rating and post it here.

This would seem to be a bit unrealistic in the case of O-linemen. In the NFL you very rarely see O-line come out for breathers. I used to play Tackle and despite being moderately unfit (for a footballer), I played every offensive down one season.

This is how in understand endurance and playing time in FOF.

100% doesn't mean the 100% of the game but the 100% of the plays that his endurance allows him to play.

Example, let's say a guy with a 80 endurance can be on the field for 10 straight plays. Setting his game time to 100%, it mens he will be in the 10 plays, a 80% means he would be on the field for 8 plays etc. So the player endurance is the first thing to look at when you want to know how much time he will be on the field, and the playing time % is a modifier.

This is an excellent and succinct synopsis of how it works.

This was mentioned in another thread, but "Endurance" seems to work in FOF as a proxy for short-term injuries. In other words, there are no injuries in FOF where a guy is out of the game for a series or two and then returns. Either he's done for the game, or "he's toughing it out" and continues to play. Endurance serves on a global level to ensure that players participate in a roughly realistic number of plays in a season. On a play-by-play basis, it doesn't always make sense.

Also, the "locking" mechanism doesn't do what you believe it does. It's only there to allow gamers to make sure chosen players stay in the slot they currently are when the scout recommend button is hit.
