Retzlaff and his Eagles were NFL champions in 1960. Both he and Hansen are members of their NFL team's halls of fame.
Missing from the list of South Dakota-born NFL players is Aberdeen Central graduate George Amundson, who was born in Pendleton, Ore. Amundson was drafted in the first round by Houston in 1973. He played the 1973 and 1974 seasons with the Oilers, and 1975 with Philadelphia. He played in 29 NFL games and scored four touchdowns.
Former Northern State standout running back Ronnie Cruz (born in Lakeport, Calif.) played 19 games for the Kansas City Chiefs from 2005 to 2006 before injuries cut his career short. Injuries also sidelined Aberdeen-born and Central graduate Josh Heupel, a sixth round pick by Miami in 2001. Heupel is now offensive coordinator for the Oklahoma Sooners, whom he quarterbacked to a national championship in his senior year.
Derek Engler, who started his high school football career at Aberdeen Roncalli before moving to Minnesota, played in 34 games (1997-2000) with the New York Giants. Engler was the starting Giants center for nine games. Kent Clausen (born in Watertown, 1976 Aberdeen Roncalli graduate) spent a couple of years with the Jets, but did not play in any regular-season games.
There have been other area and NSU players drafted, but none whom played in NFL regular-season games of which we are aware. If there are, email me at email@example.com.
