On injuries, I don't mind the frequency of CEIs, what I don't like is that they are instantly recognizable as the end of the player's career. I don't think that happened to anyone except Ray Chapman.
What I'd like to see is that we have to figure out if the player is ever going to make a comeback. With that in mind, we should see hits to current ability (and talent, if the player is younger). However, after the 12 months or so of the long injury goes by, the player should show up for work.
Now we can see if he can comeback. Players whom the game currently has as coming back after a 12 month injury should be mixed in with the true (disguised) CEIs. Some players will come back from the injury, others won't. We won't know until we play them at some level.
There should be a small chance of a Tony Conigliaro comeback, or Herb Score coming back to be a C- pitcher. Then we can decide if we want to keep the guy around.
