Off the top of my head:
10.) Wanted to improve the Cowboys’ grittiness quotient.
9.) Ceding Austin television market to the Texans, he’ll be damned if they get Grimes County, too.
8.) Replacing Jason Garrett with Tom Osborne, who needs (the other) TO when you’re running the veer?
7.) Cowboys fans can throw anyone under the bus just as good as any Aggie, why not someone who’s already used to it?
6.) Bob Gates has been secretly posting on the Cowboys.com message board. Convinced Jerry that the terrorists were going to win otherwise.
5.) Gotta have some local flavor to fill those $2000 seats at Jerryworld.
4.) Testing new grass stain remover from the home uniforms.
3.) You just don’t get that same head-snapping effect practicing with tackling dummies.
2.) Wade Phillips lost a bet to Fran and decided against holding the jiz jar.
1.) Probably expects to lose multiple games by 40 points, needs someone expendable with situational experience talking back to the opponents’ bench.
