The cap hold is not zero though, at least for 1st rounders. Their hold is dependent on the scale of where they were picked.
Second rounders I'm not sure, those might not have any cap hold as you imply.
You're right: stashing removes the cap hold that's placed on the team's books. My bad.
You may be right, but I am suspicious of this. Yabu and zizic are currently under contract with foreign teams (I believe). There's no actual mechanism to "stash" them, we simply don't sign them to their rookie contract/they don't negotiate a buyout. But if what you say is true that stashing results in no cap hold, what's to stop us from using the cap space and then negotiating a buyout and signing them to their rookie deals (given that their cap hold is greater than the generic roster spot cap hold)?
Where's Larry Coon...I mean saltover?
Edit: also the faq section you quoted said that they don't count against the cap during the regular season, not before then.
