We're going to be keeping a running list of young players and prospects that have been reported untouchable before the trade deadline this year, so you can keep track of which players are in talks and which ones apparently aren't. Obviously a report of "off-limits" status isn't definitive, but we'll just call this a useful tool for the next week or so. If you see a report or tweet of "untouchability" let me know so we can add it to the list.
