I'm agreeing with this. Kakashi would gain a lot of credit as 'Hokage' material if he were to be able to deal with Sasuke. Power differences aside, Kakashi is still more experienced, and he has the Mangekyo trumpcard. Sasuke has only dealt with it one other time, against Itachi, and Itachi's is genjutsu based so Sasuke had plenty of time to analyze the situation and break it. Kinda hard to stop and analyze a technique when it's ripping your arms off.
