Should Jansen stay in the starting lineup?

I'd have to watch the game again but I really don't recall him having any major issues in pass pro, and considering the pass rushing talent the Cowboys have that's saying something. Even Samuels had his hands full yesterday.

Heyer seems to be a better pass blocker, while Jansen still seems to be an effective run blocker. Switching them in and out based on that would give too much away to opposing defenses, but maybe start Jansen, and bring Heyer in on two minute drills and other obvious passing situations.
