Another area where I believe that the injury model is very flawed is that in
OOTP one knows immediately almost exactly how long the injury will last. IRL this isn't even remotely the case. In many instances, especially for pitchers, injuries that are essentially career enders (at least as far as a major league career is concerned) occur but it is not known for years that this is the case.
I think the game would be a lot more interesting to play if this aspect of the game was made more realistic.
