Rajshahi people wish to have their own team and have their own stadium where they can cheer their team. However, if Rajshahi wants to retain all the players who were in Comilla Victorians last season, they can simultaneously retain them in their team.
Bangladesh Premier League started in 2012, and so far they have completed 10 seasons. I am not sure how profitable this league is, but the fact that one of the well established franchises is ending their operations doesn't reflect that well on them. What makes things worse is the fact that Bangladesh is undergoing some political and economic turmoil right now. Relations with India are strained, which means that there will be an economical impact from the next season (2025) onwards.
