I'm trying to figure that out myself. Check out this link :

Scroll down to the bottom. The following line is what I use every time I create a mock, like yesterday :
Cap Space (w/Top 51 & Projected Draft Pool) $40,237,766
The above figure includes projected costs for the draft pool. The $40.mil was closer to $48mil at 10:30 PM last night when I presented my latest mock. The only other changes made are with the dead money and the rising cost being attributed to the extra draft picks we picked up. According to the above link, we now gained $6.4mil in dead money from Ogletree. Unless CAP money is yet to be added by spotrac, I can't explain the disparity.rr
