The case does not look, at a first glance to be the sort of scenario we are discussing. They obviously appeared as predators on CCTV and there's a suggestion that they additionally spiked her drink. We'd have to read more than the wiki page on this one.
It isn't identical, but it is similar enough to highlight the flaws in your conception of "capacity" and "consent". In order to find Evans guilty, the jury had to believe either that (a) the girl didn't consent, OR (b) the girl didn't have the capacity to consent. Additionally, they had to find that (c) Evans didn't reasonably believe that the girl consented and had the capacity to consent. In order to find McDonald not guilty, they had to find either that (a) the girl did consent AND (b) the girl had the capacity, OR (c) that McDonald reasonably believed that the girl consented and had the capacity to consent.
Note that the case was heard jointly, but the jury was asked to deliver two separate verdicts: one for McDonald and one for Evans. It was the same jury, hearing the same evidence at the same time, just with two different defendants and two different verdicts.
Now, Let's call the "consent" element (I) and the "reasonable belief" element (II). If the jury acquitted McDonald on the basis of (I), i.e. that the girl consented and was capable of consent, then they must also acquit Evans on the same basis. Conversely, if they found Evans guilty, then they must believe that (I) is untrue: that the victim didn't and/or couldn't consent. It is a logical impossibility for (I) to be true, given the result of the case. You're a rational person, I know this from previous conversations with you, so surely you can see that it is simply a logical impossibility for the jury to have found that the victim consented and had the capacity to consent. As such, it's simply not true that "basically unconscious" (whatever that means) is enough for "capacity to consent". The woman was quite clearly conscious in this case, as seen on CCTV and heard by witnesses, but nonetheless could not consent.
FYI, here is a detailed summary of the case, as well as Evans' appeal:

Yeah like, 'notice that they're 'into it' '. I don't think you have a good point there, there's no requirement for the defendant to show they have tried to obtain explicit consent.
As noted above, this 'burden' is actually trivial.
Yes, well, I literally said that this wasn't the same as asking for explicit consent
My point was that we need to teach people that they have a legal responsibility to ensure that their partner consents and is capable of consenting. We started this thread by talking about what we should tell women about avoiding rape. Gori the Grey raised, IMO, a really good point earlier which I think has been missed in all this. Rather than telling women not to get drunk because they might get raped, perhaps we should tell women to drink less, in order to be better witnesses to crimes such as rape.
In other words, our suggestion is that we tell people what steps they can take such that they have the best possible chances of ensuring that justice is done. I don't think it is unreasonable to teach people about their responsibilities vis a vis consent. Not merely the minimum legal requirement to avoid being prosecuted for rape, but to make sure that you're as far as possible from being accused of rape. It's not a legal requirement to ensure explicit consent in order to avoid raping someone; but neither is it a legal requirement to not get drunk so that we can be good witnesses. Being a good witness to a crime increases conviction rates. Similarly, ensuring explicit consent reduces the incidence of rape.
So if we're talking about sensible precautions we can take to reduce the incidence of rape, then I think that encouraging people to ensure explicit consent would be a great first step in the right direction.
