“My first thought, seeing the number 17 on the lapel of Cousy, is that he wore it in honor of his, fairly recently deceased teammate, John Havlicek”
I though the same, but when I checked, Cousy retired in 1962 and Havlicek was drafted in 1962, so the most they could have played together was 1 year. Still, it could be a tribute.
” A young John Havlicek played with Cousy for a short period, but has said he made a living off Bob Cousy, referring to Cousys famous passes.”
