Anderson from 08 averaged 22.59 at home and 30 away/ neutral. That's a gap of approximately 7.5 runs. It's ATG figures at home and Srinath figures away.
Funnily enough, a ~7.5 run gap is also Srinath's record home (26.61) and away (33.76 - Anderson's overall away (not including neutral) record since debut is 33.36).
If we start splicing things up, taking away Srinath's first two years and his last year where he was wretched/past it, he has a pretty respectable record too.
49 tests, 197 wickets, 27.87 overall average with 25.87 at home and 29.97 away.
Difference also being that Srinath played just under 50% of his games at home, while Anderson (since debut, not since 08) plays nearly 60% of his games at home as opposed to away/neutral.*
*Anderson has a pretty gun record in UAE (neutral) to be fair but it's 6 tests only. If Anderson had a more even record with regards to home/away matches played, he'd probably be averaging another ~2 runs or so higher overall.
Are those claiming Anderson is ATG/Courtney Walsh level ready to put Ashwin and Jadeja up there too out of curiosity?
In short, stop rating Jimmy up there with Courtney Walsh. Good/great/whatever bowler, but a tier below Walsh please.
