Donte Whitner's Value

I was wondering what the thoughts are for Whitner.  I own him, Pollard and Polamalu and I'm trying to figure out the long term value for Whitner in a Dynasty league.  Is this a fluke year and will he be replaced or this guy finally found it?

One reason I ask, is b/c I also own Gore in a dynasty league and a guy said he'd trade me S Jax for Gore and Whitner.

I think Whitner has "finally got it" and has good fantasy value. However, I wouldn't trade Gore for SJax as Steven Jackson is perhaps the most overrated fantasy running back over the last couple of seasons.
