Hehe, you're right, those are relatively high odds by my standards. But in my opinion only Mönchengladbach's game is particularly risky. Bayern have to win to wrap up the championship, so they'll do everything they can to achieve that. Dortmund are also clear favorites in their game against Wolfsburg.
Bayern Munich can win Bundesliga title later if they can not win their match this week but their players certainly want to complete the season by taking its trophy as soon as possible. After officially become a league champion, their players can freely think of summer holidays and they won't like to wait for too long time for lifting up a trophy.
After leaving UEFA Champions League, Bayern Munich won't want to delay their happy day in Bundesliga for too long time.
Unfortunately, however, the German Bundesliga is very difficult to predict this year, even games where you would expect clear winners are falling over in rows and the outsiders are winning.
In early of season, Bayer Leverkusen did not play well, lost many points but with the past amazing season, I believe many gamblers bet on Leverkusen and lost money. Except Bayern Munich, other clubs including Bayer Leverkusen have performed widly unstable in this season and it only help bookmakers to get more money from gamblers.
