Regarding adding a sportsbook, in my opinion, its not about doing it quickly, thats not what matters the most, but rather about doing it the right way and this includes partnering with a good and reputable odds provider.
Finding a good odds provider is not really a problem if they have enough budget, which I believe they do. What is more important is their readiness. We dont want them launching a sportsbook, then later putting it on hold because things did not go according to plan. That does not give a good impression to people.
I saw one popular casino here do that before. They launched a sportsbook, but after a few months, they paused it, and until now they have not resumed it. But they are still popular with their casino and slots games, so sometimes it is not really necessary to ride with the trend.
If they are not fully ready, better to focus on what they are already good at than force a sportsbook launch just because others are doing it.
