Falcons get Jackson.

Some animal's teeth get longer with age.

Seems as though once a RB joins the NFL, his "age" is determined by the number of carries over his career.

ATL swapped one dude with a few carries left in him for a dude with not-quite-twice-as-many.

Hell, Frank The Inconvenient Truth Gore seems like he's been rode hard, and everyone wonders how many carries are left in his body... and he isn't anywhere close to Jackson's carries.

Safe to say, I won't be rooting for the team with the Beaver backfield. But if they put a sheep in the end zone, those guys will score TDs like nobody's business. Just watch out for the celebration... probably don't want the kids to see it.

How the hell was I not aware of that?!

You probably did know that, Sam, but, since you're getting a little long in the tooth, you just forgot. :)

I've heard a somewhat different explanation.

As we (human beings, that is) age our gums tend to recede, which makes one's teeth look like they are longer.

Horses teeth specifically in this case.

Rats must chew or their teeth grow through their brains.
