I can't disagree more with either bold text.
Nose requires sheer bulk and ability to hold your gap. Lateral movement ability, while nice, is not as important as sheer strength and the ability to occupy blockers.
Per the second bold text sentence, Oliver was tailor made for the 3T spot. His athleticism is superior, especially his short area quickness; like as good or better than some good wideouts. And while the 3 is where I expect him to play predominantly, his athleticism will allow him to slide out to the 5T as well.
