I think calling them the 5 best based only off of win loss record and success at the WCWS is tough. If that's the criteria you want to use it's probably true...
Fine coaches, but I said to myself as I clicked on the topic, "It may well be that the best current softball coach is completely unknown nationally, because he or she is toiling away developing young girls in a local program somewhere."
I think Clint Myers has made a case for himself with his rapid turnaround of the Auburn program. He took all those players he hadn't recruited and made them into a contender team with stellar defense and a big hitting offense.
