The Packers pick 30th, its worth 620 points on the draft chart, if say for example the Washington Redskins wanted to trade up from the 53rd Pick in the 2nd Round, that pick alone is worth 370 points ( a net difference of 250 pts) to make up that difference the redskins would have to give up a player probaby, and another pick or two. If the skins say gave up their 3rd pick, 83rd Pick valued 165 you still have a net loss of 85 Pts on the "draft chart". that may or may not be enough, but I'm just illustrating the point that it's very difficult to trade up INTO the 1st Round. Cleveland did it last year much higher up, but for a player they knew they wanted, and they gave up a lot this year to do it. Thus I don't see a lot of trading going on in the first down. Lots of teams would gladly trade down, but the salary a 1st Rounder would command plus the loss of draft picks to get there would make it more difficult. A team lower then even the redskins, would have to come up with even more then that, so no I don't see a trade down scenario in the first as being likely.
Which brings me to a question. What about a Trade up Scenario? If there's a player we want no reason not to go up and get him if you think he'll be gone. As an example consider this:
Green Bay Trade Up Scenario:
An Example:
Green Bay
Get's 21st Pick 800 pts
Redskins
Gets Green Bay's
1st (30th overall) worth 620 points (net Difference 180 pts)
3rd (94th Overall) worth 124 points (net difference 56 pts)
2009's 4th Round or a Player (not sure who?)
Granted GB loses two picks this year, but if there is a player (perhaps a CB/DB) that GB really would like to have, moving up to at least 21 would likely net a better player then waiting at 30.
I'm not saying they should do this, and I only use the Redskins as an example cause I have an idea of what they might be looking at this point (and I think they'd be more then willing to move down given their loss of a 4th rounder this year and next). It might even be possible to package a player in here, and reduce the value of the picks as well. Trading within the 1st Round might be easier than trading down out of it. But again, the team you negotiate with has to be interested in doing it. It always takes two to tango.
The main question here, is what one or two players would be worth it. Either way this may not be able to happen until draft day.
