Late 1st is pretty fair. Remember, a couple of teams have already dealt their first round pick away. SJ belongs to Buffalo. STL belongs to Buffalo too. They have 3 of them, so if they don't view their Finnish goalie as the long term answer, they could use the last of those picks to secure Knight. LA Kings own the Leafs 1st round pick. Is Peterson the heir to Quick? Or would they be better off adding Knight late in the first? If you don't feel comfortable that he will be there come your turn in round 2, you can use that extra pick on him.
NYR could have TB's 1st if they win the Cup. Possibility for them as well.
Winnipeg, Nashville, Boston, Washington, Calgary, etc could all deal their 1st round pick giving another team an extra pick. That could be used to take Knight.
Knight is the only one who is rated in round 1. That trend should continue as well move forward. Don't see teams lining up to use a 1st on a goalie. Waiting 4-5 years and as the GM, you might not be around when he's ready to play. Has to be the right situation.
