26 of the 28 teams existing in the league at the time of the draft were each allowed to protect either one goaltender, five defensemen, and nine forwards or two goaltenders, three defensemen, and seven forwards. The Atlanta Thrashers and Nashville Predators had their entire rosters protected, as they were the two newest franchises in the league, only being in existence for one and two years respectively.
For teams protecting only one goaltender, there was no experience requirement for those left unprotected. For teams protecting two goaltenders, each goaltender left unprotected must have appeared in either 10 NHL games in the 1999–2000 season or 25 games in the 1998–99 season and 1999–2000 seasons combined. A goaltender had to be in net for at least 31 minutes in each game for the game to be counted against these totals.
At least one defenceman left unprotected by each team had to have appeared in at least 40 games in the 1999–2000 season or 70 games in the 1998–99 season and 1999–2000 seasons combined. At least two forwards left unprotected by each team had to have met the same requirements.
52 players were chosen in the draft, two from each participating franchise. Only one goaltender or one defenseman could be selected from each franchise. Both the Blue Jackets and the Wild were to use their first 24 selections on three goaltenders, eight defensemen, and thirteen forwards. The final two picks for each team could be any position.

The Blues have so many really good young bubble players, I would worry they would all go poof. Guys like Ian Cole and Jake Allen.
