Shit the only thing I can think of would be that Ikkaku is in Renji's position where he is getting stronger and probably knows the bankai right now, just still has to train for those several years before becoming a master at it and captain level. He said he is the 2nd strongest in the 11th. Who says anything about the VC being the strongest? They are just picked by the captain.
he said he is the second strongest MAN in the 11th division.
