I find it ironic that you mention his ING cup final performance in the same time period(which appears to be on a minefield of a pitch btw)
You didn't see it ergo you can't comment intelligently about it.
For the record, I saw every ball and the ball was moving around a bit because the pitch had a little green and it was cloudy. Nothing outrageous. Not ideal for a OD final but nothing too great. Couple that with some VERY poor batting by SA, a couple of great balls by Aaron Bird (as an aside, that was my first look at him and he was very impressive early in his spell; zippy) and the scorecard doesn't accurately reflect what happened.
I dont know what your standards are, but averaging 42 doesnt exactly qualify as bowling well for too many people
Having played a grand total of two tour games and not having bowled in a match for ages before that, probably being told before the tour not to expect much cricket and coming in with the Ashes on the line for the first time since 1989. Again, the averages tells little but the balls he knocked over Trescothick, Bell and Freddie with do. He was on a hiding to nothing and if he'd been taken apart, people would have understood considering how under-done he was.
No doubt Tait is wild (in the same match I saw him take 11 wickets I saw him bowl two of the widest balls I've ever even heard about; if you can find a picture of the Adelaide Oval, picture a bowler running in from the Bradman Stand End bowling two balls in an over which literally didn't hit the cut portion and ran into the fence under the scoreboard) but you haven't seen enough of him to know just how well he can bowl when the radar is on. I've seen a fair bit of Tait for a while now and have seen enough of Mahmood to know that you'd have to have rocks in your head if you rate them equally. Similar type bowlers, yes, but Tait does it far more consistently.
Umm Sajid has been performing consistently on A tours to India, WI and SL. Has Tait done anything like that?
Disingenuous. Australia doesn't do A tours very often (it's been almost four years, in fact; see below) and if they do, it's usually a few OD'ers. So opportunity, not performance, is the issue here.

so maybe you would like to explain why Ponting didnt bowl tait then? the only logical reason is because he didnt want to take the risk.
And that was a mistake by Ponting because it put too much pressure on the other bowlers. If you pick a guy, you should bowl him. There should be no passengers in a Test side. If they wanted a boring line-and-length'er, they should have picked Kasper because it wasn't as if he was bowling THAT badly and is a far better lower-order hitter than Tait.
The fact is, they picked Tait as a shock bowler to take wickets and not worry about the runs. The Aussie selectors can't have it both ways by picking a guy who makes no secret or apologies for the fact that he's ultra-attacking and then complaining that they couldn't bowl him because they couldn't trust him to not keep it tight. By blaming HIM for being the way he is, they left him out to dry a bit for mine.
It's not as if Tait had cut back on his pace and was hitting the corridor in the one warm-up game he got before the Test just purely to get selected. He bowled as he does so if you pick a guy for that reason, you have to live with your decision and accept it. Ponting tried to appear like he was taking risk but maybe due to fear of being the captain to lose the Ashes, he wimped out when it came to the crunch. I mean, with the rain and the fact the Aussies were 2-1 down in the series, it's not as if they could afford to be frugal with the risk-taking. They needed wickets and FAST and Tait could have taken 0/100 off 10 overs and the result would have been the same OR he could have taken 5/60 off 10 and won Australia the game too.
In my opinion, it would have been sad had England not won the Ashes because they deserved them more but baulking at using Tait is a cop-out.
