Inspired by Dravid, of course. I was trying to think of comparable performances by players whose team was on the wrong side of an absolute thrashing and could be forgiven for thinking they shouldn't have bothered.
Lamb's three hundreds in 1984's blackwash comes immediately to mind. Lara scoring massively in huge defeats in SL. Rodney Hogg taking over 40 wickets when his side went down 1-5 in 1978/79.
