Our regular season just ended and I will have the 16th pick in next season's amateur draft. I know I'm right on the borderline, if I sign a Type A guy do I keep that pick, and the franchise he came from gets my 2nd rounder, or do they get that #16 pick?

Thanks.  

16th pick and higher is "protected".  17th pick and lower is not.

*not including Type D's* - i.e. if you would normally have the 16th pick and a Type D is given to a team at #3, bumping you to #17, your pick is still protected.  Verbatim from the knowledge base "The former team receives the signing team's first round pick (or second round pick if the pick is one of the first 16 picks not including Type D picks)" - you're welcome
