Regardless of how the two players do this match, doesnt justify dropping Kasper for the reasons they gave. Despite taking a 5-for, Macgill does not look any better than last year when he went for 1/211. He started off exceptionally poorly (worse than usual), going at around 7/over for no wicket. I dont think this'll get mentioned by anyone else, but during the period where he was picking up wickets, he fell back to the flaw that got him hammered by india, WI and SL. I.E. 4-5 decent balls in an over, with at least 1 boundary-ball in between. So I'd say his stats today can at least partly be attributed to rash Pakistani batting.
If we dismiss Pakistan cheaply in the 2nd innings, few will remember the potential bowling disaster that may have resulted when Pak were still 2 for 200 odd. A scenario that had less of a probability of occuring if they had picked a proven flat-track specialist-i.e kasper.
The "sacrifice" you talk about with Watson says something about how much the selectors cared about this match. The pura cup in my opinion provides more than adequate preparation for the international scene. It was, after all, created to mimic the kind of competition and experience that would eventually be met at the test level. Bringing younger players in for the sake of "a smooth transition," ridicules the role of the domestic system and would probably better be referred to as a myth created by the media rather than a legitimate strategy.
Bringing youngsters in for the sake of experience, not necessarily because they're good enough to be in the team is poor selection if you place great importance in winning the match. Of course, I've pointed out that the selectors probably do not care as much as they could, and have thus resorted to this "rebuilding" strategy. If a country has to bring in young players to the national team to cover for future retirements DURING important matches, then quite simply the domestic system is not good enough. I do not think that is the case here.
