Tatupu was on the Patriots from 1978 to 1990 and played on the 1985 team that lost to the Bears in Super Bowl XX. Tatupu was selected for the Pro Bowl in 1986. During home games in Foxborough, a group of Tatupu fans behind the end zone held a banner entitled "Mosi's Mooses."
"They are great fans, but just to have your own section is an honor," Tatupu said in a 2004 interview with the Globe. "It inspired me to play harder because they were cheering for me and backing me up."
