I developed a 'drag and drop' depth chart page for both sorting and ranking players by position.
Link for now, I haven't added a link anywhere to the site yet. http://ibc.poweralleycircuit.com/depth_chart.php
Currently I only have a page that allows you to edit your team, I'm working on a display page where you can view other teams' depth charts.
The only catch is that it requires Javascript (should be enabled by default on most computers) and may not have 100% support by all browsers, so if you're using Opera or using a Palm Pilot it probably won't work.
As always, feedback, bugs, errors and suggestions always requested/welcomed.
