After college , Grigg signed with the Buffalo Bisons of the All - America Football Conference ( AAFC ) . Vying for a spot as a tackle , Grigg weighed in at 330 pounds . He played in the first games of the season for the Bisons in 1946 , but was benched in September because of his weight . As a joke at practice , Buffalo coach Red Dawson occasionally told players to " take two laps around Grigg " . Grigg attempted to get his weight down to 300 pounds , but was unable to do so . He returned to the lineup for an October game against the Chicago Rockets , and the Bills finished the season with a 3 – 10 win - loss record . During training camp in 1949 , Grigg and teammate Ben Pucci were sold to the Rockets . Grigg played one year for the Rockets before being traded along with Alex Agase to the Cleveland Browns , a team that had won the first two AAFC championships . Grigg played as a defensive tackle as the Browns won all of their games in 1948 and a third straight league championship . Cleveland won the championship again in 1949 , but the AAFC dissolved after the season and the Browns were absorbed by the more established National Football League ( NFL ) . Grigg continued to struggle with his weight while with the Browns . In 1948 , head coach Paul Brown gave him a $ 500 bonus for weighing in at 278 pounds before the season . Grigg , however , ballooned to 317 pounds by the end of the year . The following season , Brown gave him another $ 500 for coming to camp at 275 pounds and promised him an additional $ 500 to keep the weight off for the rest of the season . In 1950 , Cleveland ' s first season in the NFL , the team finished with a 10 – 2 record and advanced to the championship game against the Los Angeles Rams . The Browns won the game 30 – 28 on a last - minute field goal by placekicker Lou Groza . Grigg later said blocking for Groza as he made the kick was the highlight of his career . Grigg stayed with the Browns for the 1951 season , when the team again reached the championship game but lost to the Rams . He was acquired by the Green Bay Packers in 1952 , but was picked up by the Dallas Texans early in the season on waivers . Grigg played a final season for the Texans before leaving football . Later life and death . After his playing career ended , Grigg owned and operated a successful restaurant in Ore City , Texas that was well - known in Upshur County for its catfish . He sold the business after 18 years in 1972 and retired . By then , he was suffering from diabetes and living off of a disability pension and social security . " I have sugar diabetes and a few other things that go with it , " he said then . Grigg was arrested in November of 1976 for shooting and killing his 20 - year - old son Michael . Michael had been convicted the previous year of burglary and was serving a five - year probation sentence at the time . Police were called in and found Michael on the family ' s living room floor with a bullet in his head . Grigg was released on $ 50 , 000 bond . The following year , he was indicted and tried for murder . His son had been taking drugs including marijuana and valium , Grigg said , and he felt the boy could not be helped . " I tried everything , " he said in 1977 . " I thought we ' d get him straight , and then he ' d start again . He ' d get a job , then quit and spend the money on this stuff . " The jury in Grigg ' s murder trial was deadlocked 9 to 3 ; he changed his plea to guilty of involuntary manslaughter and was sentenced to five years of probation . Michael had changed because of the drugs , Grigg said , quitting his sports activities and losing his ambitions . He was kicked out of high school because his hair was too long . Grigg died in Ore City on October 10 , 1983 .
