For anyone interested in who's available and who's gone where, here's a sortable list of 532 players. If you've got insider, you can check any individual's trade rumors linked directly from the page.

The list is pretty much up to date. It doesn't have that rock resigned with the skins though, or that Noble is retiring (which makes sense, cause its not official yet).
