Absolutely. Botha has been a waste of space.
Bowled well TBF. The disturbing thing about these SA knockout losses is that it's hard to assign individual blame to any player. Yes, there is a weakness in the middle order, but dodgy middle order or not, you should be chasing totals like this and winning the occasional big game. You should definitely not be losing 3-4 crazy wickets in quick succession when the opposition puts you under a bit of pressure. The panic spreads very quickly in this team, and it's a very collective thing.
Smith (in poor form, but solid opener)
Amla (best ODI batsman in the world)
Kallis (class act, rock solid)
AB (top 3 ODI batsman in the world)
Duminy (very good batsman, would make most teams)
Du Plessis
Botha (useful economical spinner)
Peterson (did very well in this WC)
Steyn (ditto)
Morkel (didn't have a great game, but a quality bowler)
Tahir (quality find for SA)
Look at that bowling depth! Tsotsobe can't get into the side with an ODI average of 18, averaged around 12 in the last series and took 3/13 in the last game FFS. They lose these games because they all lose their heads collectively in pressure situations, especially chasing. No other explanation fits.
