Sanders was one of 16 finalists for the Walter Payton Award recognizing best player in NCAA Division I-AA football his senior season. He led the Southern Conference in all major passing categories as senior, throwing for 3,691 yards while also tying a school record with six touchdown passes against Mississippi Valley State. All 6 Touchdown receptions was to Cos DeMatteo which broke Jerry Rice's single game receiving record for Touchdowns in a game for Division 1-AA/FCS. It was also Jerry Rice's alma mater. The two were a record breaking duo at Chattanooga. Sanders also connected with DeMatteo for 13 completions for 207 yards and 3 touchdown passes at Louisville, a Division 1-A/FBS opponent. Sanders passed 367 yards and 3 touchdowns in the game. Louisville won the game 58-30,but was a career day for the duo vs a much more supreme Conference USA team. Sanders was an All-American honorable mention as a junior with 3,539 yards and 27 touchdown passes.
 Passage 2:Roland I was born around 1215 into the gens Rátót as the son of Dominic I, who served as Master of the treasury from 1238 to 1240. He was killed in the Battle of Mohi in 1241. The ancestors of the kindred were two Norman knights (Oliver and Rathold) from Caserta, Naples, who settled down in Hungary around 1097 during the reign of Coloman, King of Hungary. Roland's earliest known ancestor was his great-grandfather Leustach I Rátót, Voivode of Transylvania in the second half of the 12th century. Roland had three brothers, Stephen, the forefather of the Pásztói, Tari and Kakas de Kaza noble families. The Putnoki family came from Oliver I. Leustach II was the father of Palatine Roland II Rátót and also the ancestor of the Jolsvai, Serkei and Feledi branches. Their only unidentified sister married Maurice II Pok whom the influential baron Nicholas Pok originated.
 Passage 3:Knipe was educated at Case Western Reserve University, receiving a B.A. summa cum laude in biology in 1972. At CWRU, he conducted research with Dr. Robert D. Goldman and showed that microfilaments in mammalian cells were actin filaments through the binding of purified heavy meromyosin to decorate the microfilaments in permeabilized cells. He continued his studies in cell biology at the Massachusetts Institute of Technology, earning his Ph.D. in 1976; his thesis research focused on vesicular stomatitis virus (VSV) under the supervision of Dr. David Baltimore and Dr. Harvey Lodish. Knipe first separated and translated the VSV mRNAs in vitro to identify their coding potential. He then showed that the VSV glycoprotein (G) and membrane (M) proteins are assembled into virions by two separate pathways. The pathway for G protein helped defined the secretory pathway for membrane glycoprotein assembly and the pathway for the M protein defined a cytosolic pathway for membrane protein assembly.
