Passage 2:In 2000, Schlesinger played in all 16 games for the fifth time in six NFL seasons and second year as the Lions' starting fullback. His 15 special teams tackles tied for fifth on squad as well. In 2001, the Lions named Marty Mornhinweg head coach and the team moved away from a power rushing attack to the west coast offense. The fullback, in addition to rushing and blocking responsibilities, can also be more involved in the passing game. Schlesinger finished the 2001 season with single-season career highs in rushing attempts (47), rushing yards (154), rushing touchdowns (three), receptions (60), and receiving yards (466). On the year Schlesinger rushed for 16 first downs, the only season of his career he accumulated a double-digit total in the category. For his efforts during the season, he was voted the Chuck Hughes Most Improved Player by teammates and was also voted onto Howie Long's Tough Guy team. He was also named to the 2001 All-Pro Team by Sports Illustrateds Paul Zimmerman and to the College and Pro Football Newsweekly 2001 All-Pro Second Team squad.

Passage 3:DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments. In 1936 with Lewis MacNaughton, DeGolyer established the petroleum exploration consulting firm DeGolyer and MacNaughton, and Core Laboratories, Incorporated the same year to provide drilling core and fluids analysis. DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934.
