I still think a deal gets done before training camp.
Lawrence was the key contract for the negotiation, it pretty much set what the market rate is considering that there literally is not any statistical categories in which Lawrence is superior to Dak. Be it yards, TD passes, completion percentage, QBR, playoff wins, ect...
If Lawrence is worth $55 million a year then there is literally no debate at all that Dak's value is not at least the same. Nobody, including the Cowboys, can make any argument whatsoever that Lawrence is worth $55 million based on his on the field performance and Dak is not. The stats do not lie, and even if you want to include playoff games, Lawrence has just one career win and he threw 4 picks in that win, so again, no argument can be made that Lawrence is worth $55 but Dak is not and the Cowboys know this as well.
