The "Ram"

The St. Louis Rams have named themselves after the mountain mammal commonly associated with it's horns. Thus, the helmet looks as such:

But when you look deeper they are very aptly named. According to Wikipedia, the Big Horn Sheep, or "Ram" as they are commonly referred to, the following is true:

Bighorn sheep graze on grasses and browse shrubs, particularly in fall and winter, and seek minerals at natural salt licks. Bighorns are well adapted to climbing steep terrain where they seek cover from predators such as coyotes, golden eagles, and cougars. They live in large herds, but do not have the strict dominance hierarchy of the mouflon: that is, they do not automatically follow a single leader ram, unlike the Asiatic ancestors of the domestic sheep.

I would argue that this is exactly how the St. Louis Rams play. They tend to not play football but browse shrubs and use salt licks on the sidelines. Their running backs usually try to seek cover from such predators as the Minnesota Vikings. They also tend to not have any strict leadership... and their couch is often criticized for not following the strict domincance hierarchy of the mouflon.

Well played Rams... you've gone deep with your mascot.
