The Consistent Finisher badge is new for NBA 2K20, and reduces penalties for mis-timed layups and allows players to make layups more consistently. It is in the Finishing category of badges.
Consistent Finisher is one of the best finishing badges in the game, as it is the most effective counters to Intimidator and also generally helps makes mistimed layups that have been inconsistent this year.
Recommendation: We recommend Consistent Finisher on at least Silver for Slashing builds and on the highest level possible for other builds with low finishing stats. Besides Contact Finisher, it is a necessary finishing badge.
