I think Bartlett moved ahead of Lausanne based on Lausanne losing to White Station. The last Dandy Dozen was before the Lynx lost to the Spartans in the Chubby Andrews Invitational.
Bartlett has not loss to anyone locally, so they probably deserve to move up. With JJ they are capable of beating anyone, but also they can be beat.
Millington looks to be in the right spot. They have lost to Central and Lausanne, but they have some quality wins. They have struggled at times, but they have done enough to deserve their ranking. Millington won the Collierville tourney, so what was wrong with the coverage? The best first-round game of the tourney was Fairley-Millington. Should the CA have covered the losers bracket games instead of the finals?
White Station has some quality wins, but has losses to Overton and Houston -- two teams ranked in the lower half of the Dandy Dozen. Houston has played a tough schedule, but they still have 6 losses. You mention Overton, but they loss to Ridgeway which beat East. So, you can spin it however you like. Again, its just a poll and it will all play itself out, but I think the CA research is pretty accurate and its easy to bash on the local rag, but I think they are doing pretty good with their coverage of girls basketball.
