I love to watch my games, but I have noticed there are quite a few events that take place which make me wonder what it might look like in real life. For example, the fact that I am about 20 for 40 when my guys decide to dunk the ball. Shouldn't a dunk be relatively unmissable, minus some great defense or the occasional lazy play? Also, blocks don't get any recognition unless you're watching your box score as opposed to the shot chart.
These are the only two that are coming to my mind right now, but I'm sure there are many more interesting 'little things' that could be refined.
