This is my first tiered big board and at this point I am fairly confident my top 27 stays the same. I still have to hash out who I like at the end of the draft but included my gut reaction picks for tiers 8-10.
In this class the guys I am the most confident in as NBA players are 
Flagg, Harper, Edgecombe, Knueppel, Jakucionis, Sorber, Raynaud, Clifford, Kalkbrenner, and Clayton.
This list represents the guys who are feel are safe bets to be productive in the NBA. Maybe not as high ceiling outcomes but at their floors they stick in the league and help teams win. These thoughts will likely push me to move Kalkbrenner and Clayton up in my final board but right now I tried to balance out ceiling and floor.
