The Cowboys and Roy Williams agreed to a five-year extension worth $45 million and including more than $20 million guaranteed, a source told ESPN's Chris Mortensen. "I'm more happy to be a Dallas Cowboy than when I got my first bike," said Williams, who was born and raised in Texas and went to UT-Austin. RealGM Note: Williams 'deserved' to make $3.5M in 2007 and is on pace to 'deserve' $2.3M as the 50th best receiver in the NFL.
