What's in a number?

A lot, apparently.

Nnamdi Asomugha, the star cornerback who is in his first year with the San Francisco 49ers, offered running back Anthony Dixon a pretty penny for the number. To be exact, Asomugha was prepared to fork over $24,000 for the No. 24.

Dixon, a fourth-year running back who will make $630,000 this year, turned down the offer.

"I worked hard to get that number when I first got here," Dixon said. "I worked hard to get it off somebody else. I've been No. 24 since high school and college."

Because there are so many players on the preseason roster, Dixon and Asomugha were allowed to double up and both wear the no. 24. But now Asomugha will have to find a new jersey number ... or up the ante on his offer.

As we've seen before, NFL players will go to extreme means to purchase uniform numbers, and especially the No. 24.
