I still doubt they would want to carry 34+ million in dead cap over the next few years, but this would be workable for most teams.
On the other hand, if the Bears didn't pay the signing bonus to DK, and also didn't pay for a new Roquan contract, they may have to push in more into a trade.
Just spitballing, but would it be possible to sign and trade Ro, have a similar delay of recognition of the signing bonus, then the teams swap players and the signing bonuses effectively stay on the originating team with neither side having to take a $30 million cap hit in any given year?
