IpodKinCarter just posted a 1 hour long video on youtube on EVERYTHING we need to know about 2k13. He was their solely to test out the gameplay mechanics and he has revealed a lot of new things we didn't know about 2k13. The link to the video is here:
If you wanna see the part where he confirms flopping go to 23:45 of the video. Even though I really suggest you WATCH the whole video cause its pretty incredible all the new things he says about the game. Leave your thoughts about flopping and all of the other new gameplay features in the comments section.
