No Dan, it was pace for Bollinger. Gloss it all you want. The selectors were furious he dipped into the 120 km/hs and claimed he was clearly not match fit else he would have bowled faster.
Likewise Clark was thought to bowl too slow, hence other bowlers were preferred and he was not given the same international opportunities after recovering from injury.
Hilfenhaus dropped from first class cricket even for a lack of pace.
Bird may have been given a go due to injuries, but not a serious contender for a regular place until he gets more pace despite a test average of 23.30.
Lehman did not just create this mandate of 140 km/h with some novel thinking. There would have been far more criticism if it was novel.
I agree that performance should be a greater criteria than pace. Stuart Clark was a champion that any other team would have played - bar maybe South Africa. Ever wondered how Shaun Pollocks career abruptly ended?

I edited above some nice stuff for you about McGrath's bowling and his views on bowlers slowing down for you to view.
If you find it hard to believe that Thommo bowled at 160kmh and Lillee at 154.8 kmh because of the 1970's measurement tools (speed cameras weren't they or were they radar?) then you're welcome to fly in the face of many batsmen's accounts of facing them as against other bowlers.
