Yes. If the Cubs worked out a trade for Patton he'd be theirs without any type of restrictions. That would only be correct if Patton has passed through waivers. Otherwise another club can put in a waiver claim on Patton, and assume the Rule 5 restrictions themselves. So no, it's not accurate to say that the Cubs could flip a player to the Rox and then be free of the Rule 5 restrictions, UNLESS he's already passed through waivers. Do you have a link for that? Nothing I've seen indicates you have to pass the player through waivers to trade him. The purpose of the Rule 5 draft is to prevent teams from keeping good players in the minors when other teams are more than willing for them to play in the majors. If a Rule 5 player didn't have to pass waivers before being traded, what's to stop teams from drafting players during Rule 5 drafts and immediately flipping them in a trade, and therefore getting a player for nothing (ok, $10,000 or whatever it costs to draft)?
