The 'Dance (A$$)' rapper discussed West's high hopes for his career in a new interview with MTV News.
"[Kanye] actually told me that I was going to be the best. But I took that as the potential, because he speaks with so much passion," Big Sean recalled.
The star continued: "What he meant was, I'm his protégé, he took me under his wing. I'm in the studio hanging with him and Jay-Z, I'm in the studio with Nas, I'm in the studio with everybody, and it's like, if I don't take it past where they took it, then what the hell am I doin'?"
Big Sean also compared his own "progression" as a rapper to the late Steve Jobs's work with Apple.
"It's like natural progression, it's like evolution. If Steve Jobs would've made the same cell phone, the big-ass, dumbass phone that we be all talkin' on instead of the iPhone, then it wasn't no point for him to be who he was," he said.
Big Sean previously shared an embarrassing moment from West's past, when he disclosed that the British Royal Family once objected to the 'Runaway' rapper staying in a London hotel due to a noise disturbance.
