Silly!
The players, the manager, and expert commentators on Team Sweden and Swedish TV all commented on the 3 by 3 OT PRIOR to the tournament. None of them liked it, but everyone agreed that these were the rules, so that was it.
After the QF when Sweden lost to Team USA after more than 8 minutes OT, no one complained about the rules. We should have beaten Slovakia with 3 instead of 2 goals, and then avoided USA or Canada before the semi-finals, or scored ourselves during the long OT.
No sour grapes there...
They probably did complain about it. But nobody over here cares. The fact is everybody except the TV networks (and probably the Olympic organizers looking at their schedules and what’s supposed to be happening next in the stadium) likes the 3 on 3 rules. But such it is.
