What I think we're going to see is the same thing that the Dolphins did against the other two teams that Henne has started against.
Fins will come out trying to force the Saints to respect our passing game. If we can get some yards through the air then it keeps your defense from crowding the line of scrimmage. If we can keep your safeties from cheating up towards the line then we'll try running at you.
Yeah I know...easier said than done, but that's what I believe we can expect to see.
The flip side is that I would expect your defense to challenge Henne early and try to rattle him into some bad decisions. It may work, it may not. Only time will tell. I won't be surprised in the least if your defense pressures him into a bad performance. However, don't be shocked if Henne actually stands up to it and has a good day.
I'm not the guy to make predictions, but I do like our chances on Sunday.
