Darmstadt is delivering an intense fight against the relegation zone. I thought they would be far behind, but many of their games have been close and they have also had some good results against far superior opponents. That is why I think this is still not over for them by any means. If they can get their draws here and there and then maybe win some of the games against the teams in front of them, perhaps they are able to avoid relegation or at least secure the play-off position.
It is difficult for Darmstadt to get out of the relegation zone because they qualify for the Bundesliga without having players of comparable quality to compete with other teams. Even Koln and Mainz, who have experience in the previous season, also find it quite difficult to get out of the relegation zone because currently they have only been able to collect 10 points from the 16 matches that have taken place. There are still a lot of left in the match and maybe there is still hope for the three clubs in the relegation zone to find points.
If I'm not mistaken Darmstadt have only won twice in the Bundesliga competition this season, which means they have lost a lot of points, leaving them at the bottom of the standings with 10 points. Union Berlin is also not necessarily safe because it is only three points away from a club in the relegation zone.
