May be bit too much but I'm fan of 16 team format be it International ICC tourney or IPL so i won't mind if they give a green lights to couple of more team, if not 14. I'm not sure if its going to work out due to schedule and i'm skeptical if second tier league would be that effective in context of IPL because there is already Syed Mustaq Ali trophy running every year along with handful regional T-20 Tournaments.
Viewership is pretty low for the Syed Mustaq Ali trophy, and national players mostly avoid it. A second tier league with 4-5 foreign players in the playing XI would increase the viewership, and at the same time may give some exposure to tier-2 and tier-3 cities such as Coimbatore, Guwahati, Shimla, Srinagar and Udaipur. The English Premier League has a 20-team structure, but then it doesn't have any useless salary cap or foreign player restriction. IPL can be conducted in a similar format, but then the number of one sided matches would increase.
Starting new second tier league looks odd to me when they already have few, schedule is major roadblock. IMO the best approach would be allowing foreign players to participate in Ranji, Sayed Mustaq Ali Trophy or Domestic season similar to County Cricket. It has some challenge like salary expectation for SENA players but this could be win-win situation for every party.
- Countries like SL, Ban, Afg, Ire, Zim and associates members can also take benefit. Teams like Afg, Ire and associates members don't get to play much 4 days cricket anyway.
- SENA players can finally learn how to play spin.
- Local players quality will increase and more competitive cricket in domestic arena.
**County allow 2 players in the team, BCCI can start with 1 and see how it goes
