There are some players on over the cap that aren't on Spotrac.
DeAngelo Tyson, DT - future/reserve ($675,000)
Stanley Jean-Baptiste, CB - Practice ($525,000)
Drew Nowak, C - future/reserve ($525,000)
George Farmer, CB - Practice ($450,000)
Justin Hamilton, DT - Practice ($450,000)
Trovon Reed, CB - future/reserve ($450,000)
Will Pericak, C - Practice ($450,000)
Antwan Goodley, WR - Practice ($450,000)
Deshon Foxx, WR - Practice ($450,000)
Robert Smith, S - future/reserve ($450,000)
Brandon Cottom, FB - Practice ($450,000)
So, it looks like over the cap includes these contracts ($5.775 million) where spotrac doesn't. As far as I understand these contracts, they don't go against the cap unless the player is added to the active roster - so it looks like over the cap is playing it safe and assuming all of them make it - where spotrac just ignores them. I could be wrong - but that's what it appears like.
Other discrepancies include John Shirley ($525,000 vs. $450,000).
The other, and most glaring, discrepancy is that the websites don't agree on the estimated salary cap. Over the Cap has an estimated cap of $150,199,087, where Spotrac has an estimated cap of $154,000,000.
Thanks for the info. Guess we'll have to wait to see how the cap shakes out. Sure hope Spotrac is closer to being correct.
