I heard it said a number of times that people struggled to express in words why McGrath was so good. I think the case with Lee is that people stuggled to express why, for sustained periods, was he so bad.
In his physical prime is stock delivery was about 92 MPH, easily taking it up to 95-96 when he wanted to and he wasn't famous for being overly erratic in the same way, say, Steve Harmison was/is. That said, and playing in one of the greatest sides in the history of cricket you would have thought he would have tore a new one in every team he played.
The reality was somewhat different, even mediocre batsman found that they could get through the bluff, bluster and wannabe filmstar heroics. Despite the odd vicious bouncer (often directed at feared strokemakers like Matthew Hoggard
) I was amazed at how readily milked he was by our batsman in 05. Despite memorable cameos he may have been the worst bowler in the series with the exception of the then totally blunted Jason Gillespie.
Overall, I am afraid that Brett Lee the bowler does not stand up to much scrutiny outside the ODI arena where to be fair he was very effective.
