What happened: One relocated franchise appears under two identities in the raw count. Treating that franchise as continuous reduces Buffalo's total to 16.
Why it matters: The measure offers a historical benchmark after Buffalo ended its playoff drought in 2026. Consistent treatment of relocated clubs will be critical when comparing the Buffalo Sabres with older franchises.
By the numbers: Buffalo averaged 1.73 rounds per playoff appearance. Its 17 opponents equal 32.7% of its 52 rounds, or 30.8% when the relocated franchise is counted once.
What to watch: A league-wide count using one relocation standard will determine Buffalo's place in NHL history.
