Much of this comes back to the same reasoning behind locking down players whose game is rained out. Our actual scoring is based upon official, overnight statistics. Completely independent of this, we get real-time stats during the days. However, this feed of data is subject to completely different constraints and guarantees, and is not official. If we get incorrect overnight statistics, we can correct them after the fact. However, if we get incorrect real-time data, and you change your roster based upon that, we can't put the toothpaste back in the tube and correct it; there is no room for, "I wouldn't have put that guy in my lineup if I'd realized that my other catcher actually played.", or whatever similar situation might arise. Now imagine the situation where one owner in a league gets caught by an inaccuracy in the unofficial real-time stats and another doesn't; that is an angry owner.  In situations like this, one of our guiding principles is to try to make sure that we can apply the same, consistent rules to all owners. If we ended up effectively basing the official scoring on your league on unofficial real-time data, we couldn't reliably guarantee that fairness. So even if the current state of things will sometime lead to arguably sub-optimal consequences, it is the same for all managers.
