I think these are related. I expect they plan to have conversations with agents of some more expensive players today. If they sign here, they may need to restructure more (e.g., Sewell and ASB). If not, they may be good with just a partial restructure of Goff's deal. Either way, I'm sure conversations have been had with all three of ASB, Goff, and Sewell's agents about the possibility. Usually contracts don't even give the player a choice, since it's all positive for them (more guaranteed money has little to no drawback for the player).
Also, they don't have to make restructures public. They may have been done for weeks and just not released the information.
Same for Decker, depending on what they do in the next 48 hours will probably determine whether he's released with a post-6/1 designation. Though maybe they're hoping cooler heads will prevail? Or that if a deal doesn't pan out they'll pay him more? Who knows. The next 72 hours will tell us a lot.
