Yes, Anderson can bowl the inswinger, but aside from that Steyn has more advantages:
- Simply put, Steyn's record is up there with the greatest ever, Anderson may bowl excellently for the rest of his career but still end up +26 in terms of average. It's hard to say you are a better bowler overall if you have such a big gap in terms of stats. Even in the ICC rankings, Steyn is almost 100 points ahead.
- Steyn has been worldclass for at least 5 years now, Anderson has for almost 2 years only.
- Steyn is marginally better in terms of pace, can crank it up to 145+ when needed.
- Steyn's has won matches in the subcontinent, something Anderson has yet to do.
- In terms of big standout performances, both have performed excellently at home, but nothing Anderson has done compares to the 10-fers Steyn took in Nagpur and Melbourne, those are the sort of performances greats are remembered by.
