Whitner at Free Safety was talked about at times on rumblings over the offseason, but with the success last week, it might be a main stay in the defense.

I am not sure if that means Ko is not coming along as well, or if it means a more rotational system at safety, i don't know. But, if Whitner has more success, and overall we are harder to deal with for offenses, than i am all for it. How about you guys?
