Here is the issue.. If Moultrie was this sure fire BPA that had few red flags and was without question the BPA then I absolutely agree you take him..
Here is the issue.. He has SERIOUS red flags about him. He doesn't have a motor, scouts question his true dedication (Earl Clark anyone), he is 6'11 and athletic, yet he averaged LESS THAN A BLOCK A GAME.... And his rotation defense is as bad he it comes for someone that big and athletic, it goes back to lack of a motor/desire, which are two of the biggest red flags you can have as a high NBA Draft pick..
He has some good things about him too, but when you hear time and time again he may not get much better than he already is at the moment, it is a scary propitstion. The bottom line is athletic 6'11 PFs dont last outside the top 5 unless there are serious issues, and Moultrie has them. Will he turn out to be great? Maybe, but he is a high risk pick, when there are other options with just as high of ceiling and arguably higher floor than Moultrie.. That is all I am saying..
