Yeah our German team is on a roll at the moment. 3rd win in a row, 3rd win by 19 or (mostly) more points and 3rd game of scoring at least 105 points. That's actually crazy. So many points in 40 minute games says a lot. Still we have problems on defense sometimes cause our teams occasionally is slacking a little bit. Against teams like Serbia for example we can't have that happen. But yeah, the start is more than promising and I have high hopes for the for the rest of the group games and the start of the KO stage.
Until now, Germany hasn't played against a similar caliber/strength team. No offence to the fans of those teams, but I really doubt that there was anyone who believed that Montenegro, Sweden, or even Lithuania could win them. Germany's offence looks on fire, but as you said, their defence needs more consistency.
