Is this some sort of joke? Lol. Think of it this way. Kimmimaro was ill, but he was still had to focus while fighting GENIN Rock Lee, Naruto, and Gaara.
Hanzo is a freakin' KAGE. You really think some 16 yr. old with a kekkei genkai is going to take on someone who defeated a battlefield of countless shinobi AND the Jiraiya, Tsunade, and Oro while they were high jounins? Honestly, Kimmimaro is barely a low jounin level.
