ok i just read something in another board that struck me. kakashi is like a super genius coz he became chunnin like at the age of 6... yeah? (this i already know) and also im guessing that he didn't have the sharingan until.... lets says late 20's (his age is like 30's now imo) and so that means he has only had the sharingan for like... 5-6 years? which means most of his skills and stuff that he has learnt was from when he was small. i think this is a significant sign that he is most likely the strongest.

</div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td>QUOTE </td></tr><tr><td id='QUOTE'>sasuke could see everything but he couldn&#39;t copy because he wasn&#39;t trained to fight that fast. later on its mentioned that he could go at lee&#39;s speed but only for a short period of time, because he doesn&#39;t do anywhere as close as much training lee does. </td></tr></table><div class='postcolor'>

Sasuke could copy it. He just couldn&#39;t block it coz he was too slow. how else was he able to do the lion combo?
