Heck, Bosa offered to take one or the other - but no top 5 pick since the slotting started has given up both. It's common for them to get both. Frankly, I don't understand the Chargers in this. If they are so worried about not having an offset, then why would they have taken Bosa in a deep draft?
If I were a free agent, this would make me less likely to want to sign with the Chargers. Some negotiations preserve cap space - but realistically zero is at stake here. This is Spanos hoping to save a little bit of money by deferring payment of the bonus - but it will count the same for the cap. So basically to save a tiny fraction of the value of the franchise, they are hurting the Chargers for 2016 and possibly future years. Showing that Spanos would rather make a little extra money from the cash cow that is a NFL team instead of winning.
