Sage signed a two-year extension (meaning he was already signed for 2009 and the Vikes modified the deal to include 2010 and 2011). The deal was reported for $9 million. His base salaries over those three seasons total $7.6 million, so I'm guessing his bonus was $1.4 million, which would accelerate in full to this year's cap if the Vikings cut him.
Interesting scenario actually... I wonder if the Vikes did cut him (which I doubt even with Favre and Tarvaris on board), he could in theory re-sign with the Texans and compete with Dan Orlovsky as the #2. Who knows, maybe Sage pulls a Quinn Gray if Favre is added?
It's probably all moot since there are now
reports that Favre is saying he'll remain retired.
