That's interesting, because the narrative at the time was that England only got a sniff because of the two Tests McGrath didn't play (Edgbaston and Trent Bridge) they won both. But in reflection, what you're saying stands up. England had 3 guys average over 40 with the bat and 3 guys average under 30 with the ball. Australia had 1 over 40 with the bat and two under 40 with the ball (Warne 19, McGrath 23).
But there were so many moments, as there has been in this series. Maybe that's what makes cricket more than averages does. The dropped catches (Warne at The Oval, Bairstow ad nauseum, Root x a lot, Stokes off Lyon in the first Test), the no ball wickets, the controversial run outs (Bairstow, Ponting run out by Gary Pratt), injury dramas (McGrath, Wood not playing Tests 1 or 2)...it's just insanely intriguing.
