V K, you are right in your direction.
I think the committee deciding replacement for the Redskins is carefully deliberating in order to capture the true spirit of criminal metaphor.
There are many!
I just explored synonyms for criminal and got directed to various animals.
Some animals are vicious, others are greedy, others are cunning.
I recall that the TRiUMPhant winner of the replacement skyscraper for the Sun Times building in Chicago delivered 50 different architectural drawings to the city officials to win approval.
Likewise, a selection of suitable helmet logos seems like a wise way to go.
“... outright sneaky, and will take anything that’s there for the snatching. Here are seven animal kleptos.”
bumblebee
sperm whale
skua
hyena
magpie
burrowing owl

Or, you might consider the mythical swamp creature, Bunyip.
Personally, I prefer the magpie (magpie press) or the hyena (vicious beast, laughs as he does his dirty work)
