Put this in the other thread, so might as well here.  Writeup I did yesterday on the cap ramifications of the deal.
Heres a quick breakdown: Porter's contract called for $7 mil in guarantees, and he'll make $1 mil in base salary this year. So by trading him, they'd incur a net cap hit of $6 mil this year. Assuming TO's deal would call for him to recieve a $12 mil bonus over 7 years, and he'll make the vet min salary, TO would have a cap hit of a little over $2 mil. That would mean the Raiders would spend $8 mil of their cap this season on the trade and signing TO. Im not sure TO's bonus can even be prorated over the 7 years, as the CBA is not extended past 2008(or 09) currently. It may only be 5 years, which would result in TO's cap number this year being close to $3mil, and the cost of the trade being $9 mil.
		
		
	 
I think the Porter side of the analysis is wrong on a couple of fronts.First, his deal included $7M in GUARANTEES, that doesn't necessarily mean it was all signing bonus.  In fact, I think it is worded that way precisely BECAUSE there was a less than usual amount of signing bonus if any.  Only signing bonus gets pushed into the current year's cap when the player is traded or released.  If he has a guaranteed salary of $4M next year for example, his new team would be required to pay that and thus would come out of THEIR cap rather than the original team's.  I have never heard exactly how much signing bonus money they gave to Porter if any.
Second, I think that since it is after June 1, even whatever "pushed forward" signing bonus money would be split between 2005 and 2006.  That's the case for released players, so I assume it would be true for trades as well.
