If there is no context, those informations will have a wrong impact. Someone who was a NT coach a long time ago might not be worthy to be the current NT coach. Do we inform the voters about the NT experience with other NT ? This is valuable experience too. Candidates may sometimes inform in their speech they were part of a NT staff, but this can't be officially displayed on the election page as there is no official proof. Here again, this might be valuable experience
I would give this infomation about experience in NT in short, compact form, e.g. like this: what season, what NT, record, trophy (if was)
Everybody could evalute by yourself, if some experinece in particular NT (even if many seasons ago) is valuable or not.
Of course, current ranking of a team and nationality of candidat should stay too. It's also some kind of information, which in pack with others can be useful.
Generally, in my opinion a voter should get a compact pack of the most useful informations. I believe that then potential voter would be able to vote more reasonable. Only information about current ranking is not enough for sure amd lead to false conclusions.
To be honest I'm a scepticist in regards of links to speaches. I think even direct link will not encourage most of users to read them. Even now speeches and debate's threads are pinned on the top of forums and highlited on red (access for them are relatively easy) and still are ignored by most of voters. Maybe only some kind of short message like motto, main idea, or main advantage (e.g. I was part of NT during last 4 seaons) could be noticable and readable.
