The cap will return at some point, though. It's not a good idea to spend with reckless abandonment. It'll catch up with us sooner or later.
Barber and Marc C will help the cap a little, but Williams will hurt the cap IIRC.
Writers keep mentioning a $12 millionish cap hit if we drop Roy but I keep writing to them and no one has produced numbers to validate it. From the last Watkins article I read:
If the Cowboys release the under-performing Williams, they would take a $12.9 million cap hit. Williams said he wants retire with the Cowboys but is due to earn a $5.1 million base salary, and his cap number is $9.4 million. It's doubtful he would take a pay cut, if asked.
Watkins makes the mistake of assuming Roy's $4.3 milllion prorated bonus will extend over the final three years of his contract, making it $12.9 in total bonuses. He is missing the fact that bonuses have not been allowed to be prorated beyond the 2012 season, making the number closer to $8.6 million.
But lets pretend Watkins is right. If we cut him this year we take on an additional $3.5 million against the cap. Now we have to cut him next year and save only $2.5 million in cap space (Roy will cost us $11 million against the 2012 cap accord to Watkins).
OR
We cut Roy after the new June 1 date, whenever that will be. This allows us to take the supposed $12.9 million and split it between 2011 and 2012. We end up saving $3 million against the 2011 cap and $2.4 million against the 2012 cap, or all of Roy's 2011 base salary.
