I can assure you the odds are even. It may appear to favour the opposition more because you think "Hey, that's not fair!" when they get the ball, and tend not to notice as much when it happens to your team.
OK, assure me. How are you so sure the odds aren't weighted? I mean, it would make sense for them to be since blitz gets so easy to win after a while.
Either way, it doesn't make the game difficult, but maybe a little annoying.
