cowens would prob make the all time celtic list. just searching bref for Cs as sorted by WS, it's a pretty sick list:

its...
bill russell #1 (i think this one is automatic)
larry bird #2 (i think this one is automatic too)
havlicek
parish
mchale
pierce (very deserving #6)
sam jones
bob cousy
dave cowens 9
bill sharman (shouldnt count bc 1952 like wtf heh)
seems good. after them it's don nelson, cedric maxwell (maybe points for doing radio), tommy heinsohn (celtic through and through + coaching + tv!)
