This trade rests entirely on thost two first rounders you mentioned. Are they in the 2013 draft? How high are they likely to be. I'm very high on the top end of this years draft class and IF these picks could land you in the top 5 that makes a HUGE difference in how I'd value this deal.
Others have already given you solid advice. You can not just throw in guys like Kunitz, Burrows and Jagr.....I made mistakes like this when I first joined a keeper and it took me years to claw back solid NHL talent like that.
Here are a few tips:
-Do not get caught up in hype surrounding the upside of prospects. For every 70-80 point upside player who pans out there are 4 searching for thier first 60 point season. You'll get lots more useful seasons out of Burrows and Kunitz...do not throw them away.
-Do not throw in older players just because you don't see a place for them in the future of your franchise....leverage fair market value for them or just sit tight and wait for the trade deadline when the top GM's make their play for the win and are willing to give up more for a guy like Jagr.
-Do not pay for prospects with question marks unless the price is right (eg. Kuz is a buy low candidate only. Do not pay for his upside under any circumstances!)
-Scour these boards for tips on players you might be able to snag for free...wait for those names to start becoming more well known and flip them as the hype builds. There's no easy way to rebuild a franchise.
