That's not really true. You are talking about 2014 only. It "costs" a lot more to keep him another year with a restructure in 2015 and beyond. The 8.5m they save in a 2014 with a restructure has to paid for. Plus he has two 500k workout bonuses, one in 2014 and one in 2015.
It is not cheaper to cut him this year for 2014 and 2015.
We've been through 2014 many times.
His cap hit in 2015 is far from certain but could easily be restructured or renegotiated down again.
He could also be released in June next year which is how you'd free up max cap space since a June option this year is unrealistic and also places the burden on 2015.
Since there really isn't a single weak side DE on the roster and the team badly needs the 9 mil from a restructure in March they will almost certainly go that route.
Then they try to draft a replacement that can take back up snaps.
If nothing falls to them in the draft they are looking at the FA market and paying well beyond rookie money.
It is illogical to assume Ware costs us some 18m cap hit when we fully know that number will be lowered one way or another.
And it is clear the cheapest way to handle 2014/15 is push money to 2016 while adding cheap rookie contracts to balance it out at the position.
