The answer is very speculative and subjective . So there is no concrete answer . Q&A thread is not the right thread to discuss this . I would suggest speculate away in this thread : )
When Ichigo was being healed by Orihime, what did Grimmjaw did to the 4th rank espada (cant spell his name well) from interfering ?
Spoiler for manga:
He sealed him away in a caja negacion (box of negation), a normal annacar would be stuck in there forever but someone of espada rank would only be in there for a few hours (grim seems to think some where between 2-4) currently it has been only about 1 hour since then in the latest manga chapter.

When the fifth and awakened Nel started to fight. The fifth espada stated that Nel was third espada many years ago before she was castaway. But Aizen has been around less than a year. And there has been espadas only as long as Aizen has been around. So the time line doesn't match.
How is it possible that there were espadas before Aizen came to the Hueco Mondo? Or am I misunderstanding something here?

Spoiler for answer:
Espada have been around for a while, all the Privaron Espada were Espada before Aizen came to power, but afterwards they lost their rank as Aizen could create more powerful arrancar using Hoyoku
