Rebuilding is not a dirty word. And Carpenter and Skubal are luck nothing more or nothing less. To say there is no value in drafting high because you got lucky is foolhardy. Studies have shown time and time and time again far more Hall of Fame level players are drafted high than found randomly in some late round, no matter the sport.
and the average war of guys to make the majors out of round 1, is nearly 7. For every other round its not even half that.
Of course there are plenty of exceptions such as Carpenter and Skubal. But, to dismiss being bad and say being average still means you can build a championship level club though the draft is not backed up by stats or reasonable strategy.
