Read captaincy history without mistaking diagrams for tracking data
What does this comparison actually establish about leadership and playmaking?
Select seven milestone stops, inspect illustrative passing paths, and compare an 11-name captaincy subset. Documented appointments are different from tactical fixtures: this independent page is not an official NHL tool, a full franchise archive or an evaluation of leadership quality.
Passing paths, primary-assist rates and slot percentages are authored illustrations without game logs, denominators or tracking provenance. They do not establish player rankings or causal effects of captaincy. The table combines draft-to-appointment and acquisition-to-appointment intervals; its average does not compare like-for-like development histories.
Try a worked example
Backes’s 2003 draft and 2011 appointment give 2011 − 2003 = 8 calendar years; the original 5 has been corrected. The stored intervals now total 57 across 11 rows, so the unchanged average calculation exports 5.2. This is a subset average using mixed starting events, not a franchise benchmark.
Distinguish the appointment from the chosen subset
The team announcement identifies Thomas as the 25th Blues captain and fifth original Blues draft pick to receive the role. Blues: Thomas captaincy announcement
This page contains 11 selected names and four marked as drafted by St. Louis. Those are counts of its own data, not totals for franchise history. Selecting a table row changes the comparison panel, while filtering only changes visible rows. A comparison can therefore remain selected even when the filter hides its row.
Use a consistent definition of years to captaincy
Backes’s team-hosted retirement account documents a 2003 draft and 2011 captaincy appointment. Calendar subtraction gives eight years, not five. Blues: Backes retirement account
The team Hall of Fame dates MacInnis’s captaincy from 2002; NHL’s quarter-century retrospective dates his Blues career from 1994–95. Calendar subtraction gives eight. Blues Hall of Fame: Al MacInnis NHL: Blues quarter-century teams
For drafted players, the starting event is their draft; for acquired players, it is an arrival event. Calendar-year differences are not exact elapsed durations, seasons played, years on the NHL roster or proof of organizational development. Other legacy interval fields retain their original values and are not individually certified by this review. No universal runway rank is computed.
Interpret timeline stops and season labels
Thomas’s extension was signed in July 2022 after a 77-point 2021–22 season; the deal began in 2023–24. Blues: Thomas extension announcement
The 2021 marker denotes the start of the 2021–22 breakout season, not a completed 2021 calendar-year total. Milestone labels combine dated events with season summaries; the point tile is an example associated with that stop, not an annual time series. The 2022 stop now shows the documented preceding 77-point season rather than the unsupported 65.

Treat the rink as a teaching schematic
Each milestone swaps fixed SVG paths with two or three authored curves from a central hub. Line width and color come from the fixture; they are not measured pass frequency, completion probability or player movement. The progress bar advances by marker index divided by six, so seven unevenly spaced years receive equal visual steps.
A primary assist usually refers to the last assist before the goal; an assist rate needs a defined sample and game denominator. Slot-pass accuracy also needs a definition of the slot and attempted versus completed passes. Neither denominator nor a tracking source is supplied here, so the numeric tiles remain explicitly illustrative. There are no authored relationship weights or calculated leadership scores.
Know what champion, export and Reset mean
The official 2019 winner record includes Pietrangelo as captain and Thomas, Schenn and O’Reilly on the championship roster. NHL Records: 2018–19 Stanley Cup winner
The Cup filter uses whether the listed player won with St. Louis, not whether they captained that Cup team. JSON includes the active milestone, selected comparison and statistics calculated from all 11 rows, regardless of the visible filter. The copied summary is a fixed overview with scope notes, not a snapshot of the current milestone. Reset returns to the final marker, Pietrangelo and All; there is no editable data import or live update.
