TBH, on a turning wicket Lyon probably a better option... sounds like O'Keefe is a Vetorri type bowler, demanding but not likely to rip through test lineups - Vetorri of course offered us so much more, genuine bowling all-rounder (averaged 40 with the bast for a few years I think), captain etc
Lyon has shown he can finish tests off in the right conditions, something Vetorri couldn't often do (and so I assume O'Keefe) - but you'd have thought a bowler with that record would be in the squad and play under certain conditions (ahead of Beer, Doherty, and that kid that played in England)... Lyon had some shabby treatment and deserves some loyalty now
