We definitely need to sign or draft another QB...definitely.
One's season should not go totally down the tubes due to an injury at the position...most teams have a backup that can hold the fort for a few games or at least give you a chance to win.
We have nothing but developmental guys...that's not what you're supposed to have for your backup QB.
My answer is yes because the Cowboys are making a SB run this year. To lose Drew Bledsoe in the middle of this year (yes, he's tough but injuries happen nonetheless) would be a disaster. I'm not throwing rocks at Romo or Henson here but I want a guy with experience ready to come in should something happen.
