What is captain level? If you say that Aizen was above captain level that means that you can be so strong that you can't be a captain. Yeah, ofc then you would have a higher rank but that doesn't seem to be it. So what I'm saying is that captain level doesn't have a roof but a bottom. If by some coincidens a new shinigami decides to joing the Gotei 13 and he is stronger than any other shinigami then he wouldn't be "above captain level" but "merely" the strongest captain.
