RT doesn't have logic to calc division standings correctly

Be warned.

If you use their Commissioner service to manage your league, and you utilize divisions they do not have the tie breaker logic to calculate them in the correct way. They use their "overall" standings tiebreakers only. Divisional display is just a report that's been re-sorted after they calculate standings.

They are aware of this flaw, but refuse to fix it.

This can and will impact who wins divisions who makes the playoffs if you rely on their standings display.

For example:
12 team league, 3 Divisions.
1st Tiebreaker - Winning %
2nd Tiebreaker - Head to Head (Winning % against all tied teams)
3rd Tiebreaker - Divisional Record

Its this 2nd tie breaker that is the problem.

In all sports leagues that use divisions, divisional ties are broken 1st to calculate standings within the division, then tiebreakers are applied across divisions for things like wild card spots. Its what assures that you never have a team that finishes 4th in their division win the wild card over a team above them in the divisional standings.

It also eliminates adding an unrelated random element to tie breakers. If you're breaking to determine who wins the NFC north between the Bears, Vikings and Packers, you don't make those teams record against the Broncos relevant to the tiebreaker. (But this is EXACTLY what RTSPORTS does)

Here's what RT does. In the commissioner service, you'll notice that there's a toggle on your divisional standings display. That toggle shows overall standings with no divisions...this is their standard pay league view of standings. What RT does is use that list to break ties between teams with the same record, THEN they just reassemble the divisions. Its backwards, and therefore wrong. They legitimize it by putting this little qualifier in their tie breaker wording (Winning % against all tied teams)

Here's an example:

This is what division standings should look like...

Blue Division
Team A 8-6 Overall 5-1 Division (1-1 vs teams B and C so 1st place based on 5-1 division record)
Team B 8-6 Overall 4-2 Division (1-1 vs teams A and C so 2nd place based on 4-2 division record)
Team C 8-6 Overall 2-4 Division (1-1 vs teams A and B so 3rd place based on 2-4 division record)
Team D 6-8 Overall 1-5 Division

Red Division
Team E 9-5 Overall 4-2 Division
Team F 7-7 Overall 4-2 Division
Team G 7-7 Overall 2-4 Division
Team H 6-8 Overall 2-4 Division

White Division
Team I 9-5 Overall 4-2 Division
Team J 8-6 Overall 4-2 Division
Team K 6-8 Overall 2-4 Division
Team L 2-12 Overall 1-5 Division


This is what RTSPORTS does...

Blue Division
Team C 8-6 Overall 2-4 Division (2-1 vs teams B, C and J. 1st place in this division because they beat team J.)
Team A 8-6 Overall 5-1 Division (1-2 vs teams A C and J. 2nd place based on 5-1 division record)
Team B 8-6 Overall 4-2 Division (1-2 vs teams A, C and J. 3rd place based on 4-2 division record)
Team D 6-8 Overall 1-5 Division

Red Division
Team E 9-5 Overall 4-2 Division
Team F 7-7 Overall 4-2 Division
Team G 7-7 Overall 2-4 Division
Team H 6-8 Overall 2-4 Division

White Division
Team I 9-5 Overall 4-2 Division
Team J 8-6 Overall 4-2 Division (RT uses this non division team to break the tie in the Blue division)
Team K 6-8 Overall 2-4 Division
Team L 2-12 Overall 1-5 Division


Again...NOBODY does this in leagues with divisions. The tiebreakers are "worded" correctly based on what they do. But what they do is wrong, and I have to assume lazy programming. Their pay leagues don't incorporate divisions, so they just calculate standings the same way they do in those leagues...then for the commissioner service they just resort what they've done to make it "look" like divisional standings.


For reference...here's the NFL's official tie breaker rules, which is a good resource for how ties should be broken.

To Break A Tie Within A Division
If, at the end of the regular season, two or more clubs in the same division finish with identical won-lost-tied percentages, the following steps will be taken until a champion is determined.


Two Clubs
Head-to-head (best won-lost-tied percentage in games between the clubs).
Best won-lost-tied percentage in games played within the division.

Three or More Clubs
(Note: If two clubs remain tied after third or other clubs are eliminated during any step, tie breaker reverts to step 1 of the two-club format).

Head-to-head (best won-lost-tied percentage in games among the clubs).
Best won-lost-tied percentage in games played within the division.


The only time they need to break ties across divisions is when they look at wildcards, and look at the first rule....

To Break A Tie For The Wild-Card Team
If it is necessary to break ties to determine the two Wild-Card clubs from each conference, the following steps will be taken.

If the tied clubs are from the same division, apply division tie breaker.


Translations...when breaking ties...ALWAYS apply divisional tie breakers first. And divisional ties aren't broken with non divisional teams.

Now...what could be done to fix it? For leagues that use divisions, they need to break ties within divisions first. Then they can use their system to break ties across divisions. Its really that simple.

I submitted a request to fix this last year, and I've seen a couple other posts from years prior that ran into this issue, but RT declines to fix the issue. Sad. This site used to be the top innovator for fantasy football.

Why even have divisions?

In the NFL it is done for travel purposes.
