Standings prediction:
SRH
CSK
KKR
RCB
I think KKR will make it because of their all-round quality. They've got a pretty balanced team when you look at it and have different profiles to shine in different moments. Whether it's going boom-boom in the powerplay, consolidating in the middle overs and going berserk at the end, they have players suited for all scenarios. Their bowling is alright too.
RCB have a similarly balanced side and probably the two best T20 batsmen on the planet to go with it. Their middle order can be a bit suspect at times but when you have Kohli and ABD, who needs a middle order? More importantly, their bowling has gone up leaps and bounds this season. They'll make it over MI.
MI arguably have the best squad out of all teams fighting for the two spots but they've made a mistake in playing Pollard so much and it has cost them games. I don't think they can make it past RCB, they don't have the momentum for that. Rohit Sharma's form is a bit of a disappointment too.
KXIP and RR have fought with courage in the first and second half of the season respectively but simply put, their squads and starting XIs lack quality and balance. For RR, it is a lack of batsmen in a very simple sense. They just have 5 or 6 recognised batsmen most of the time, this will backfire massively at one point or the other. KXIP have issues all over the XI and they should probably try bringing Miller to shore up their batting. Manoj Tiwary could probably play as well, he's your typical IPL veteran who can perform when needed. When they have Gayle in the XI, they're fielding with essentially 10 men. The other day he couldn't stop balls that were a few centimeters from him at short third man and gave up at least 3 boundaries as a result. That's 12 precious runs and a lot of momentum gone. That's the problem with him - if he fires, he fires in a massive manner. Otherwise he's a huge hindrance. RR's bowling is "okay", nothing more than that. KXIP have quite possibly the best captain in the tournament (or second best at a stretch) but their resources don't match up. They have just three bowlers of top 4 standard - Ashwin, Tye and Mujeeb. There's no chance teams make top 4 with such average bowling attacks (like in the case of KXIP and RR) unless their batsmen perform miracles, which is what Buttler/Rahul/Gayle have done.
Amidst all this, I've already said this before and will say it again - DD are a potential title-winning side if they can keep their batting core. If they can keep their top 6 and improve their bowling (they should primarily focus on this in the next auction, Morris coming back will help too), they'll make top 4 with ease and they'll be the favourites in one-off matches due to their fire power. I genuinely hope this team stays together and improves.
