Drummond and Lillard are CLEARLY the two front-runners. They have had the most impact on the court this year.
Davis has been good, but not as good as them. Sorry, but that's just the truth. Look at their games, look at their numbers. Davis has a higher ceiling than either of them, but as of the way they've played this year Davis just hasn't been as impactful a player as either of them.
If you are putting Davis as number 1, you are doing so out of potential, not out of what has actually happened this year.
So Davis I will put at 3. Sully and Kidd-Gilchrist should be next (the latter has been massively underrated by getting inconsistent minutes on a bad team).
