There are ways to make both injuries and EEs more intelligent in this game, and I’ve talked about them both. They won’t likely do anything with either of them, because they would require significant changes to the game engine, which they are either unable or unwilling to do, short of another big 4.0 level update.
For EEs, if they’re not going to make them more intelligent - and I mean make the tendency to want to leave early a scoutable trait for recruits, then have recruits declare independent of each other, which would result in undrafted FAs as well - then they should leave it alone. It hurts to lose a guy early, especially one down low. It’s supposed to hurt. That’s the game. This is not a college basketball coaching simulation if elite recruits aren’t at risk of jumping ship. If anything, they should leave more often, and in the manner laid out above. But leaving it alone is fine, too. If you coach at D1, you learn the difference between a player who is a 4-year player, and a player who might leave early, and you develop contingencies for the latter, if that matters to you. *That’s the game.*
Injuries are kind of another beast. They could be done more intelligently for sure, but they could also just be removed completely, and that would also improve the game. They happen so infrequently, the only function they serve as it stands is to p!$$ people off. They are not tied to any coaching choice, their occurrence and the consequences they bear are entirely random. The only thing that you could say kind of matters is that durability plays a part in how long it takes a player to recover from injury, but since they happen so infrequently, coaches are rightly told to completely ignore durability anyway.
The way injuries should work is that low durability players should see nagging injuries as the season wears on, and start to play at 75-80% past mid season, especially if they are playing tired in individual games, playing past their stamina thresholds. Catastrophic injuries that take players completely out of games should only result when coaches ignore those nagging injuries (continuing to play guys long minutes at 75-80%). If that can’t be done, injuries should just be tossed completely.
