ESPN News reports the Cowboys have signed safety Ken Hamlin. No details reported yet. I will update as I get more information.
Update [2007-3-23 16:18:25 by Grizz]: From Adam Schefter:
I'll give Hamlin credit for one thing; he sure has a lot of confidence in his abilities. He's betting he's good enough that after this year he will be able to capitalize in next year's free agency market. Otherwise, I would've thought he would hold out for a multi-year deal. He must not have been able to get anything close to what he wanted on the free agent market, so he’s betting on his ability to jack-up his worth with a good year in Big D.
