Can implies a good possibility when everything points to him not being able to lift a finger to certain Jedi and Sith.
I respect Revan as a character as well as how powerful he is. But canon states that Revan doesn't really have a good chance at beating Vader or Kun. Not trying to be hateful. I'm only following what is canon.

im an optismist. i believe in all possibilities. sidious killed his mentor out of cowardice. could he beat him one on one? he must not have thought so. and a bein his calibur died from bein thrown over a railing by a dying man. wow ok uh force levitate? im just sayin revan is smart and could formulate a plan that could win. 1% chance is still more than 0
