I don't see how your link supports your position that intent will be easy to prove. Getting nervous at a nightclub doesn't prove intent to murder, that I can see.
Long Post Warning -
If you're not serious about discussing this on any real level you will likely want to dismiss this as too long, but don't bother wasting my time with announcing it because I really don't care. If you really DO want to talk about this with me, a former Minneapolis resident AND customer of that bar, then take a minute to really read what I have to say please. Otherwise don't bother.
You're right, it doesn't, in and of itself.
What it does do however, is interest the prosecution into discovering other evidence that proves a link between the two men's interactions with each other, seeing as how both worked the same kind of job at the same club.
Chauvin worked outside at the door and Floyd was a bouncer.
The prosecution might dig up evidence that the two had bad blood and that might lead to further discovery that establishes the fact that Chauvin might have thought he could settle a score and get away with murdering him to settle it.
None of that is outside the realm of possibility between two men working security.
It may even be a rather typical issue in the industry.
From my own experience as a former professional rock musician playing in a band, I came to know bouncers and security pretty well, because we were also their responsibility as well.
Thus once you've been doing this awhile, you begin to learn a bit about their personality types.
I've known more than a handful of bouncers who had bad blood between them.
And in a couple of cases it was partly a racial thing and in other cases it was just a fragile male ego thing, thus one very deadly serious and the other quite pathetic and laughable.
I do recall the night we played a club near Lake Winona, and the bouncer wasn't too keen on a couple of black girls that came to see us play, and first break I went out to the parking lot and found them, pissed off.
I'd had eyes on one of them and was confused as to why she had left suddenly after making it very clear she dug me.
The bouncer...that's what it was.
Goddamn redneck, nigger jokes, then the n***** jokes turned downright evil.
The only reason they had stuck around is because the one wanted to talk to me at the first opportunity.
So the whole point in this is, what one has to believe in order to rule out a case of bad blood between two tough guys working security at a club is a mental stretch that would span the diameter of The Sun.
Id' bet fifty bucks that's going to be discovered in short order by the prosecution and will be featured in the case, not only by the club owner's testimony but by bunches of other relevant witnesses as well.
El Nuevo Rodeo was mainly a hispanic club but they rotated their musical bill of fare because The Twin Cities are very diverse and very open for the most part.
The suburbs? Maybe not quite as much but Minnesota's pockets of redneck bigotry are matched by some very unique small towns that have played prominent historical roles in the abolitionist movement and which also played prominent historical roles in desegregation and black enterprise stretching back to the Nineteenth Century.
The point in that is, club people know their people and they know their clientele or else the club goes out of business.
El Nuevo Rodeo catering to a lot of different races and cultures is a cornerstone policy that must be endorsed and supported by all employees, so if a few of those employees had knowledge of any friction between these two men, it's gonna come up at trial.
