Got some more info on Winston's deal, and the media info was lacking specifics, but it wasn't inaccurate.
Cap page has been updated.
Winston received a $6 million signing bonus and has a $2 million roster bonus in 2009. I don't have the exact date of the roster bonus, but I would guess that it would probably be around 3/15/09. Also, Winston's $2 million base salary in 2009 is guaranteed, bringing the total "guarantees" to the $10 million as reported.
The rest of this $30 million deal comes from base pay, so Winston will have to presumably keep his starting position to keep earning the pay.
2010 & 2011 - $4.5 million base per year
2012 & 2013 - $5.5 million base per year
His yearly bonus prorate is $1 million as the team will start the prorate in 2008... not that we currently have much reason to think Eric won't play out this contract, but in case you wanted to figure potential dead money if he were cut in another couple years.
