I just laid this out in another thread.
While it does save us money THIS year, it makes the probably of cutting him in 12 months even more painful.
Before this adjustment to his contract he was looking at a 13 million cap figure in 2013. A 9 mil salary (up from 1 mil this year), the 2 mil signing bonus, and a 2 mil roster bonus.
Basically they doubled down on his remaining roster bonus, which makes releasing him in 12 months trigger an absurd 10 million+ cap hit just to tell him to buzz off.
So, now with this change he is looking at a cap figure probably around 15 million. I will give it the Shane "Manning Guarantee" that Kevin Kolb will not make that cap figure seem remotely acceptable.
I hope they use this extra money very wisely this season, because barring a miracle its going to really plug us in the corn-hole in 12 months.
