Would the maturity and development of HUDF-JD2 not be another kink in the big bang theory?

"One of the most distant galaxies ever studied is more massive and mature than expected, astronomers announced today. The finding suggests some galaxies grew up much more quickly than conventional wisdom held.

The galaxy, named HUDF-JD2, is seen as the universe was only about 800 million years old. The universe today is about 13.6 billion years old."

Why not assume that there simply was time for it to develop because there was no big bang, rather than changing the theory of galaxy development?

I also found this:

But I'm not really qualified to evaluate it :-/

All the best trob

P.s Sorry if you've been through this already.
