I think we could get a better player via trade than with the 10th pick
Who? The draft is not as deep as previous years. Picks 3-20 are really a crap shoot. It took Wideman and the 15th overall to get Horton. I wouldn't trade the 10th overall for a player like Weiss or Ribiero.
Stoll for Roszival wouldn't be the worst trade ever, but I'm not sure where he exactly fits in. Do you keep Anisimov in the bottom 6? Christensen staying on Gaborik's line to start makes the most sense to start the season, regardless of what centers you bring in.
