By feats the team are still incapable of beating Akainu. But this could be because they've had no challenge since the time skip. They could very well be strong enough to beat him. They'll need to be if they intend to screw with Kaido or Big mom.
I was thinking exactly of that moment when I posted. If Marco and vista (and Crocodile) can't do it, I don't think the Strawhats can take it yet, although again, they haven't shown their true power post time skip (which is taking a bit long to show in my opinion) however if they are to take on Kaido, I think they'll need to be able to take down at least an admiral in the very near future.
