I'm not saying that isn't a good package - or value wise is a fair deal - it's just not what a team like Atlanta would want.
If they are giving up a top-5 player in the league, then they'll want more. Top prospects, a first, and a player like Kessel or Kaberle.
For an unsigned Kovalchuk that is a great deal for Atlanta and I see no reason they wouldn't want that type of deal. No doubt they would like draft picks as well, but it'll be tough to beat that offer as long as he refuses to sign.
