What happened to Tennant? I thought he was next in line to take over at center?

O-line is just average.
One of the best passing games in the league, yes.
To me, a good O-line can run the ball just as effectively as passing the ball.
Not the case with the Saints. We've got the backs to do it, and still not getting it done.
Bring this up again when we start consistently grinding out 100-150 each week.

Our constant telegraphing of plays via personnel groupings kills most of our opportunities to run the ball effectively.

As an example, when Sproles is lined up deep, he's expected to be the dump off receiver, which telegraphs pass. All our best runs are student body sweeps using Sproles, because the defense isn't adjusted to that kind of play.

When PT or Ingram are in, our overwhelming tendencies are to run, so adjustments are to run blitz, controlling the edges for any (highly unlikely) cutback. Neither PT nor Ingram bounce away from play designed holes, so if the O-Line doesn't create an improbably hole given the defense's reaction to personnel groupings, then we won't run effectively.

If we split either out wide like we do Sproles, then we may get more favorable matchups. But we don't so we won't.
