I personally don't respect John McClain as much of a source. The only things he seems to know are what the Texans spoon feed him. He consistently gets things wrong like that 20 million quote. He couldn't differentiate between what the team spent last year (~140 million), and what the team counted against the salary cap (~118 million). Signing bonuses of JJo and JJ pushed that number up, but they are amortized over the length of the contract. Anyways, he does seem to screw up the nitty gritty details a lot from what I have read.
Ok sowe both agree John McClain is unreliable. Cool.
Here's the problem though, none of the respected NFL guys are saying we have 28 million or whatever number you think it is. None, except a few guys on messageboards. I don't doubt that John Clayton could be off by a few million, but I don't think he's off by 20. Same with Florio who pegged us around 5 million in free space, and Andrew Brandt, etc etc... The only certain variable I see is the 2012 cap total, which as stated above hasn't been released. Most of those projections are going off the 2011 number of 120.3 million. If it goes up 5 million, we probably have a bit more to work with, but don't count on it yet.
You know now that I am thinking about it I could be over-simplifying it. I'm basically subtracting what the 17 FA counted against the cap in 2011 and assuming that even though salaries will increase in 2012 it won't increase enough to exceed the $28+m the 17 FA's made last year will free up about that much space. It sound plausible when I thought about. But at the end of the day we need to know the 2012 contracts to make a sound calculation. And I do not have that (so I cannot say how much we have).
Look, I hope you're right and the Texans have 50 gazillion dollars to spend, but I just don't see it happening. If you have a good source that says otherwise, please link it, cause I haven't seen it.
I do not have a source that lists contract other than rotoworld and sportsrac. I'm not sure how reliable they are. I just know we had 12 FA's going into the season and 5 people went on IR. I just estimated the 17 salaries and gave the low estimate of $28m. But of course we do not have a firm source to indicate the 2012 contract, which are probably more important than the $28m.
