Haven't looked at the Czech game yet but I do think both the games tonight go over the total - worst case it's 1-1 and you get a push.
Don't have a good enough handle on Canada if they that good after the jitters of the 1st period being over they've settled down and they continue to dominate or not.
Lastly, having that goal differential count makes a team push right until the end - and unlike the NHL where you'll mail it in a few nights, these guys aren't playing 100 games for their country - it's just a few, so those that really want to put on a show can, and will do so.
