Passage: By the 1920s, SCGX was doubling annually and had emerged as the "fastest growing grain market in the world"; transacting 22 million bushels in 1928 (valued at $336 million in 2018), resulting from its location in the heart of the Corn Belt and self-imposed standards before the Grain Standards Act of 1916 including species admittance and non-mixing. However, its growth was limited by shipping rates. With the trucking industry and Interstate Highway System not yet developed, SCGX was constrained by monopolized railroad rates, primarily by the Great Northern Railway. Exhausting their bargaining power with the Interstate Commerce Commission, SCGX President Charles C. Flanley directed future lobbying efforts to unlocking barge navigation of the Missouri River. His initiative was stalled throughout the 1930s by the Great Depression and Dust Bowl. In 1938, a renewed thirteen year campaign led by Secretary William Henry Marriott finally opened commercial navigation of the Missouri River and helped establish the Missouri River Basin Project, which included development of the Gavins Point Dam. The alternate transportation succeeded in breaking the railroad's monopoly. By the 1970s, SCGX was among the largest exchanges in the world; transacting over 100 million bushels annually (valued at $1 billion as of 2018).

Passage: The Texans responded to the 2010 poor defensive showing by firing defensive coordinator Frank Bush, secondary coach David Gibbs, linebackers coach Johnny Holland, and assistant linebackers coach Robert Saleh. Kubiak, a ball boy for beloved former Houston Oilers head coach O.A. "Bum" Phillips in the 1970s, hired long-time friend, and Bum's son, Wade Phillips to take over as the Texans' new defensive coordinator on January 5, 2011. Phillips became available after being fired as head coach of the Dallas Cowboys halfway through the 2010 season. Phillips was allowed to bring in his own assistant coaches. The Texans signed two high-profile free agent defensive backs, Johnathan Joseph and Danieal Manning, and used their first five draft picks, including two in the second round of the 2011 NFL Draft, on more defensive players.

Passage: It was founded around 1072 as a Benedictine priory by William FitzOsbern and his son Roger de Breteuil, 2nd Earl of Hereford. FitzOsbern had been granted the Lordship of Striguil by his second cousin King William in gratitude for his support in the Norman conquest of England, and was responsible for starting the building of a new castle overlooking the River Wye on the border with the kingdoms of Wales. At the same time he established a nearby monastic cell, so as to collect rent from the lands within Gwent which he had granted to his home Priory of Cormeilles in Normandy. By the early 12th century, the monastic establishment, on a ridge overlooking the river about 300 metres from the castle, had the status of an alien priory in its own right, though it probably never held more than about 12 monks. It superseded an earlier Augustinian priory located about 2 km away, which was dedicated to the Welsh saint Cynfarch (or St. Kingsmark), a disciple of St. Dyfrig.
