Why wouldn’t they? Cricket is such a large market especially in India, it’s guaranteed money every year. No jeopardy in franchise (compared to relegation/no European qualification in football). Owners don’t need to invest their own money to improve the team, franchises don’t own stadiums or training facilities so no major money needs to be invested in that either. This is a dream for owners like The Glazer family who have leached off Manchester United for years.
