Does Dallas Cowboys Owner Jerry Jones Want a Do Over?

Did Jerry Jones make a fatal mistake that could set the franchise back 5-10 years?

Last year the Cowboys Owner decided pay Jason Garrett top dollar and make him the next in line to get ... hired/fired. Should the Dallas owner/GM/President have kept Tony Sparano instead?

Garrett has yet to get an offense going that is full of all-pro players: Tony Romo, Terrell Owens, Jason Whiten, Roy Williams, Marion Barber and the entire offensive line. Obviously injuries are part of it, but this offensive machine began to sputter near the end of last season too.

Tony Sparano inherited a Dolphins team that only won just a single game last year and has already won 5 games this season.

Should Jerry have allowed Jason Garrett to walk and keep Tony Sparano as the heir-to-Wade?
