I feel there was a touch of arrogance about the decision.
The resting the bowlers theory doesn't make sense to me as if we had put the English back in, i strongly believe they'd be all out by this point and our bowlers would be in the sheds putting their feet up while we at most bat to get the last few runs and have the opportunity to start their recovery a day earlier.
Putting the English back in also places the emphasis on them to get a result. This Adelaide test is one they would've targeted as a win so to play for a draw and go to Perth down 1-0 would almost seal their fate for the series. Instead, they have a chance to level the series and take some confidence into the eastern tests.
