I think you are right, looks like they've settled for therams.com, so they don't need those other names.
Anyway, after seeing your comment, I was curious to see what the rams.com might fetch if it was just the name of an animal. So I did a search on valuate.com of other farm type animals, and it seems they range between around $100-200,000. Therefore, since rams is only 4 letters, it is probably at the upper end of that range, although valuate gives it a price of $116,000.
In conclusion, rams.com is still a valuable name, although it is unlikely to ever sell for the kind of money that the LA Rams could afford to pay.
