# update the stats billboard on the team page
ws.on 'updateTeamStats', (json) ->
  { teamId, stats } = json
  updateStats $(".team-stats[data-team-id=#{teamId}]"), stats

@diasdavid can you take this one too? The stats on the team page should update without a refresh when the deploy counts (etc) change.

@railsjedi, @diasdavid is not going to have time to get to this one. Let me know if you can't figure it out, and I'll do the needful after you're done updating the page.
