Jax has won only when they have rushed for over 100yrds and Ten will be the best Rushing D they've faced yet (and probably the best overall D).
Chris Johnson and the Titans offense is far more capable of quick scores than Jax.
Titans have 3 more INT's and 1 more FF then Jax.
Being a Philly fan I watched that whole Philly @ Jax game, and the Jaguars were completely unimpressive.
