Football draft 
"Simpson was drafted by the American Football League's Atlanta Falcons, who got first pick in the 1969 draft after finishing 1-12-1 in 1968. Early in his NFL career, Simpson struggled on poor Buffalo teams, averaging only 622 yards per season. "

This part of the article doesn't explain how he got from Atlanta to Buffalo (or maybe Atlanta is just a mistake). If he was traded to Buffalo or however he got there, it should be mentioned.
