The idea that moving up in the draft will require a top prospect simply doesn't fit with what the historical cost has been.
If you go back over 20 years to the Pronger deal that Burke swung, the first thing you notice is that trades to move up in the top 5 don't happen very often; but when they do, the cost to move up isn't that high, and almost never include a player going back the other way.
Once in a while, we see player/prospect for pick deals like the Schneider trade last year, but when one team is trading its own first rounder to move up a few picks, the additional cost isn't usually too steep.
Here is every "move up" draft deal made since 1993 involving a top-5 pick...
1993 : Hartford traded with San Jose to move up from 6 to 2 for the additional cost of picks 45 & 58.
1998 : Nashville traded with San Jose to move up one spot. The Preds gave up picks 3 & 29 and received picks 2 & 85.
1999 got a little crazy. Burke didn't move Vancouver's own third overall pick because he needed that for Henrik, so he first needed to swing a deal to get another top-5 pick. Vancouver traded Brian McCabe and either their 2000 or 2001 1st round pick to Chicago for pick 4. Once he had the additional asset, he swung two more deals to move from 4 to 1, then from 1 to 2.
Vancouver traded with Tampa Bay to move from 4 to 1 for the additional cost of picks 75 & 88. Then, Atlanta traded their #2 pick and their 2000 3rd round pick for the #1 pick.
2002 : Columbus traded with Florida to move from 3 to 1. The only thing Florida got in return was the option to swap picks with Columbus in the 2003 Draft (Florida ended up with the first overall pick in 2003 and did not exercise their option).
2003 : Pittsburgh traded picks 3 & 55 plus Mikael Samuelsson to Florida for picks 1 & 73. This is the only top-5 "move up" trade to involve an established roster player as part of the deal.
2004 : Carolina traded picks 8 and 59 to Columbus for pick 4.
2008 : Toronto traded pick 7 plus 2 conditional picks (either a late 2nd in 2008 and a 3rd in 2009, or an early 3rd in 2008 and a second in 2009) to the Islanders for pick 5.
