I can't speak for other people who play this way, but for me, I chose this way because the way I used to play it is no longer possible. My big thing is to have rosters correct(guys on the real life team), so let's say Ortiz gets traded in real life to the Orioles, I want to make that trade on my game......but I like to play with fantasy injuries.
Well, this year they took out the loophole where you could play with RC on and still have fantasy injuries. So, I had a choice to make....play with rosters that wouldn't be exactly right and have fantasy injuries, or play with RC on and make all the day to day moves. I didn't think I would like doing it, but I actually have enjoyed it.
