HOW TO KNOW IF A CARD SHOULD BE GOOD IN NBA 2k21 MYTEAM - YouTube
This video just goes over stats, badges, and animations (tendencies too) to look for in a card. Stats such as 3 pt, lat quickness, speed, block, driving dunk, badges like hot zone hunter, clamps, rim protector, tendencies that are high in dunking and on defense, and animations that involve pro 2 and showtime dunks. This video gives a brief overview of what can help you all with a card, but I tried to give a lot here as well.
