Not all of the things they did this year to create cap space can be done next year. Specifically pay cuts for Cam, Tyrann, Wilson, and eventually Hill, can only be done this year since they are all in the last year of their contracts. IIRC, that's already around $16 million for Cam and Tyrann and I think could be around another $10 million for Hill.
Maybe this is for some sort of big trade, although I haven't heard that anyone that has a big salary is available, but I think it's more likely to try to get guy like Allen and Scherff on one year deals in the $8 to $10 million range which they likely won't take until at least June 1 if they are still on the market.
The less likely possibility is that they are clearing space to trade Carr, but it's for this year after June 1.
At the same point after missing on Ward and Cupp, they may have decided that they will just roll the money over to make the cap easier to deal with next year.
