Nas is great cause he stood/released amongst Goats Kane, G Rap, Pac, Snoop, Jay-z, 50, Eminem etc... even during Wayne's reign while being able to remain hot and never running out of skillful steam, not being the hottest out during the weakest/lowest point of quality/skillful music in rap.
Basically, the standard is extremely low. That's why Drake shining.
Think NBA players averaging 4.5" tall then a 5.8" comes around. He'd look so tall=Drake.
