Hi, I'm a long time JL user, translator and supporter.
I deeply regard developer's work been done on JL, and I'm sure And_One, julienV, comraden, timoline and other's work will become useful in future, but it doesn't look likely that by the start of next season we'll be able to use a Joomla 3.x working version. Nothing to blame anyone, they've already done a lot!
I've found that Joomla Sports Management extension is being actively developed, it's working with some issue on 3.6 but I'm confident bugs will be squashed.
If you need to convert db tables to JSM ones, there's already a feature dealing with it and the developer is currently working on them, but he's looking for JL databases (0,9x, 1.6 or 2.x) to test with.
