It hasn't been all dreadful though. Shami and Kumar have bowled really well.
1st ODI
Shami 4/55 - 1st spell 4-0-16-2, 2nd spell (PP) 2-0-11-1, 3rd (death) 1-0-19-0, 4th spell (death) 2-0-9-1
He bowled well up front and in the batting powerplay, taking wickets in both spells. Got tonked by Anderson and Ronchi, but then came back to bowl two amazing death overs. Should have been bowled out.
Kumar 1/38 - 1st spell 7-0-24-0, 2nd spell 1-0-6-0, 3rd spell (death) 2-0-8-1
Was expensive in his first over but came back to bowl 6 overs for 17. Bowled exceptionally well in tandem with Shami at the death.
2nd ODI
Shami 3/55 - 1st spell 4-0-28-1, 2nd spell (PP) 1-0-13-0, 3rd spell (death) 2-0-14-2
A little expensive up front, got dealt to by Ryder but then got him out. Rough PP spell, but NZ had just came out after the delay and were going for it. Had another great death over taking two wickets for only 3 runs bringing NZs momentum to a halt. Even a 11 off the last was a decent result.
Kumar 1/43 - 1st spell 4-1-19-0, 2nd spell 1-0-1-0, 3rd spell (PP) 1-0-15-0, 4th spell (death) 1-0-8-1
Another good spell up front, got tonked in the one over he bowled in NZ power play, then came back and bowled a good over at the death.
Sharma has been crap and needs to go. Ashwin and Jadeja haven't really trouble NZ too much as they have generally bowled in the middle period where NZ have worked them around taking little risks, due to some good starts (and pressure being let off by Sharma)
But Shami and Kumar have been superb.
That's quite exhaustive. However, in all of that, there are a few things about the Indian bowlers I'm not too happy about. Or now that India's off the World #1 ranking, not happy at all. You've broken up Bucky's bowling in spells, and I feel across them, there's a lack of wickets- he has taken only two wickets so far. He hasn't really looked tight and stifling, but merely escaped being tonked a lot because batting sides haven't risked much. In the death overs, though, we saw Ronchi walk down the track and smash him straight, twice. That's not very encouraging for a strike bowler. In his entire career of 28 games, he's taken only 32 wickets- not enough, surely, and his average has skyrocketed into the 70s from the beginning of the Australia series. The extra wickets a bowler can take in these overs do make a difference, D/L or otherwise.
Compare that with Shami's 37 wickets in 22 games, of which 27 came in his last eleven, after his recall against Australia. I like what I've seen of Shami so far, but his economy rate is rising to Umesh Yadav levels, and he may be dropped as a consequence. I like it that he's got a very, very impressive strike rate, much better than Ishant's, bowls decently fast, and also has an effective short ball. However, he's got caned a lot on flats, which may not work out for him, though he's chipped batting sides a lot. He's also the one bowler who's actually doing very well since the Australia series began. Hopefully he'll keep bowling at this pace.
The others, though, have been poor. Ashwin's had a horror run, and as an India fan, I hope he's back in form, as he's the one decent strike spinner we've seen play for India. Jadeja's had one chance too many, and figures say it all- raw or dissected. He's crawled to his 100 wickets, while the likes of Lopsy, Broad, Anderson, Johnson, Clint, Junaid Khan (none of them all-time-great quality) have raced to their marks thereabouts, and Southee has made his mark faster in at least ten games less. He's been dreadful in his last eighteen games, and he's practically never missed a game. Hardly good enough for World #1. If he's in as an all-rounder, his batting figures are terrible (and angry fans think Rohit Sharma is mediocre), and the bottom five has seen very little action in the games he's got. I won't say anything about Ishant- other fans have done the dirty work, and he isn't immortalised on internet jokes. Of this bunch, only Ashwin can stay- the others are past it. Let's not celebrate mediocrity any longer if we want the #1 ranking back.
