Known as Coleslaw, a spin off his last name, Colclough played college football at Boston College, one season as a defensive back in the Canadian Football League (CFL) with the Montreal Alouettes in 1959 and nine more with the Patriots from 1960 to 1968, including the AFL's inaugural 1960 season.
His 17.7-yards average per reception ranks third in franchise history and his 39 touchdown catches are fourth on its all-time list.
His career highlights included a seven-reception, 142-yard, two-touchdown performance in a 45-17 romp over the Denver Broncos on Sept. 16, 1961 at Nickerson Field.
In 1970, Colclough partnered with two of the most eligible bachelors in professional sports, Derek Sanderson of the NHL's Boston Bruins and Joe Namath of the NFL's New York Jets, as proprietors of the popular "Bachelors III" dating bar in downtown Boston.
After retirement as a player, Colclough served as the head coach at Boston State College in the 1978 and 1979 campaigns.
