It's not just Ponting though, is it? It's the selectors as well. It doesn't matter how many wickets MacGill gets, if they decide they only want one spinner, Warne is ALWAYS first choice. In the 11 test matches where they've both played together, MacGill has taken 60 wickets to Warne's 48 and at a much better average. Warne is undeniably a far better batsman and fielder than MacGill, but as far as bowling ability goes, I don't think Warne should automatically be first choice.
