Naruto's first few fights were some of the worst in the series.

Naruto vs Kiba: Naruto gets pummeled. Naruto gets back up. "Don't underestimate me. I'm going to be hokage. Believe it!". Get pummeled again. Flashback. Farts. Somehow wins

Naruto vs Neji: Naruto get pummeled. Naruto gets back up. "I'm going to be hokage. Believe it!". Gets pummeled again. Flashback. Naruto uses 9 tails to kick Neji's ass. Pretty much proving Neji's point the whole fight.

Lee vs Gaara. Orochimaru vs Sasuke. Kakashi vs Zabuza. All better fights
