It warrants scrutiny, but I don't think you can immediately claim they are cheaters and that no proof of collusion is needed. I'm not a fan of deals like these myself and I wouldn't object to a world if they wanted to create a rule with regards to this (type A/B signings cannot be traded until after the draft takes place would be the simplest, probably). But as things are written, if someone decides it is a good strategy to sign a bunch of Type A players with the intent to flip them, this does not appear to violate the rules. There is an example prohibiting the signing of "questionable" Type A players and there is another example that appears to reference signing a Type A and trading it back to the team that received comp picks, though that example abuses the English language enough that it could well be misinterpreted. CS should be able to determine if a trade was discussed before signing, correct? If so, let CS look into it and blackball them if they did collude, but if not....I just don't think greed/opportunism rises up to the level of collusion.
