If you do not have any team members, you can no longer become a Bronze Team Leader with SVP (Sales VersaPoints) + AVP (Action VersaPoints) only.
To become a Bronze Team Leader now, you must have at least one first-level (1st. generation) team member who is at Executive Affiliate 2 level.
The changes were announced in a newsletter last month. Here's the link to the new requirements: http://news.sfimg.com/2015/11/19/new-team-leader-qualification-added/
