IPL is adding two more teams which means we will have more matches in already heavy schedule ipl. I don't think players are going to have some rest in T20 leagues dominated year. India has done right thing by giving rest to king kohli in T20 series and first test against NZ. Lyer n Gill on day one have performed well.
They want to add more time which means the tournaments will be extended and i do not expect the quality of the matches to improve by increasing the number of teams, but the opposite will happen in situation like this. What ever it is we will see the big drama show and since the team members keeps changing curious to see how will captain the side for the two new teams.
Increasing the team number doesn't affect the quality of the tournament in any means, only the tournament schedule gets extended. Among the entire sports league played around IPL is among the top 10. This has come as a result of perfect organising. In between some issues arise and two teams weren't allowed to play the IPL. If it is a drama this could've never been this successful.
But, I feel the more a tournament gets extended its importance decreases. Now after these two teams the tournament would bypass 90 days schedule. The only benefit would be that we will be able to see new talents that were left out by the previous franchises. The longer IPL runs the more BCCI will earn that is the motto. It will also affect international schedules as there would be less space to accumulate international matches.
