I do not disagree with you main point, but I do think your way of getting there is weak.
Maryland, you imply, was not worthy of being 4th. However, they did prove to be worthy of that rank by end of year (or very, very close) - weren't they. In the early season, the team with 3 freshmen beat the more experienced team (on the road) that was ranked 4th due to what they were expected to and did do.
Maryland thought they could handle Boston straight up and got pounded. By the time, they adjusted to focus on shutting her down, it was too late. UConn had the much better plan and focused on her early. They did a good defensive job early, but their offense couldn't take advantage of the good defensive effort.
So, was SCar's potential tournament run with 3 freshmen questionable? Of course. As were the potential runs of Baylor, UConn and Maryland whom the freshmen had beaten.
Alas, the tournament never happened,
