I think Andrew is imagining a slightly different scenario:
- Jammer A jumps the gun slightly
- Jammer A gets yelled at by the referees to fall back and to allow Jammer B to take the lead
- Jammer A assesses the movement of the pack, personnel packages, etc., and decides, 'screw it, i'm going to keep skating, take a minor, force the jam to re-start, and drain some time off the clock.'
Then before the re-start, some of her teammates could swap in and out of the pack. Sort of like an extra 'time-out' for Jammer A's team, at the expense of a minor, plus it might tick a few seconds off her teammates' penalty time in the box.
Yes this is a nefarious embedded option for Jammer A. It's never happened.
Some leagues would put the lost time back on the period and penalty clocks. That's not explicitly not in our rules, but it's a good idea and I would support an executive decision by any head ref to do it, especially if Jammer A attempted such a nasty tactic to preserve a lead with time ticking down at the very end of a bout. Also missing from the rules is any prohibition on swapping out blockers in between starts in cases like this; you could certainly make a strong argument that teams should not be allowed to do this.
Referees also always have the option to assess penalties for unsportslady-like conduct. And minors assessed to jammers can be pretty costly as well.
