I don't need to name anyone, seeing as I'm not comparing King Rohit with anyone. If you think 30 is a good score, great. India's win/loss record in the last year is testament to that sort of benchmark.
Scoring 50, 105, 32, 65, 26 does show consistency. You can’t expect any batsmen to get 50+ every innings.
It doesn’t matter if you aren’t comparing Rohit with anyone. But if Rohit is inconsistent, then you have to name some batsmen who are consistent according to your criteria (unless there are none in the history of cricket).
