Freiburg looks stronger than they are if you are having a close eye on the Bundesliga. I know I am not in the position to argue here, since I am losing in the Bundesliga pools, but still it is a result that is closer to reality than Freiburg being 5th most of the time.
Yes you are right that Freiburg is actually quite strong but they cannot be consistent, for example this season they can be in the top 5 or 4 but for the next season they will look like they are declining, that what makes Freiburg just an unstable team and their performance with the results in the Bundesliga will only depend on how strong the other team are.
2022/23 Freiburg finish in 5th place and 2023/24 they dropped by finish in 10th place, now they are back in the top 5 and this competition will be interesting until the end of the season and Freiburg can still compete for place in the top 3.
Freiburg is usually exciting team in Bundesliga while their performance has never been consistent which is the biggest problem but in this problem they are doing good job which is good, but their defense is having serious problems which are not helping them for keeping things on target. Surprisingly they are having impressive performance in last 5 games with 4 wins and 1 draw while their defense also done amazing stuff and concede no goal which is another big achievement now things are looking good for them to have finished into top ranks this could be big boost for them.
With the poor run of Frankfurt now few teams are feeling good as they can go for better spots while RB Leipzig is had the worst time which is also another plus point and advantage but here now game is going to be balanced because all teams needed consistency without this it's not easy.
