Burgess vs Rapp

Just looked up the cowboys game box score stats.
Burgess lead the team in tackles.
So my question is, do we stay with him and use Rapp on passing downs as a LB/box safety?
And while I'm on it, why is Jones on the field on
3rd and long.
In the SF game, he was isolated on De Bowl.
What would be wrong with Gervase and Rapp as LB's.
Cuzz what scares me more than Evans at LG is
3rd and 84......

Of course IDKS

Go Rams
