TMF I think bagels in practice does mean a lot, Borg was probably exerting at around 75% and he still bageled the entire team. You have to think the Romanians were fighting their hearts out there for that one game and they couldn't get it. No tennis player wants to be bageled in a live pro match or a practice set.
