Whenever I hear Eminem stans say that Em ended Ja's career, I always correct them by saying it was 50 that ended Ja's career. Nobody can tell me one line that Em said to Ja that was on par with Ja's line at the end of Loose Change. He struggled against motherfukking Ja Rule. As a matter of fact, most of Em's disses have been weak. Yeah, we can name drop "Marshall Mathers," "I Remember," "The Sauce," and "Nail in the Coffin" but all of those disses were aimed at ICP, Everlast, and Benzino. He would go at Canibus infrequently, he sent his crew, D12, to diss Royce - and they got bodied, he never responded to Cage or Evidence, and he sent everyone he knew be it 50, Busta, Obie Trice, D12, and even Dr. Dre to diss Ja Rule when he couldn't put him down for good. The fcat that MGK might have been the first legitimate rap opponent that Em went tick for tack with is kind of amazing. Off the wax, Eminem is not a tough guy in the slightest. I remember that story that his bodyguard told where his face turned white(r) when Suge's men confronted him at the 2000 Source Awards, and then a few years later, yeah, he did stand up to Suge on the video shoot for "In Da Club" but there were more Shady/Aftermath folks than Death Row in that regard. He was more built going after Moby than most rap artists.
