Chargers now expected to take Manning
We often see NBA teams trade the rights to players on draft day, but the NFL's rookie salary cap pool complicates things.
Once a team drafts a player, they are allotted money to sign him based on the pick number. The entire system works on a slotting scale, so obviously the Chargers, picking No. 1 overall, will be allotted more money to their first-round choice than will the Giants, who pick fourth.
