How long you been rhymin has nothin to do with it. Snoop, Jay Z guys like that been doin it for how long? and they seem to get wacker and wacker the more they do it. You either got it or you dont.

As far as him writing his freestyles... look at the battle against Supernatural.... in the 3rd round when Nat refused to rhyme to that one beat then did the biggie impression Juice came back with the "tried to hit Revolution on the 3-way, even tried to bring his own muthafuckin DJ" line which is clearly not written considering it would have been meaningless had Nat not refused the beat and thats sharp as hell to think of off the head... then he hit him with the "impressionisit" line in reference to Nat doin the Biggie voice.... again no way it could have been written... and the stuff that is written he has very clever punchlines... better than 99% of most MC's....

you can say Juice has no heart or passion for rappin all u want but dont be ignorant and deny skill
