I agree counting on Dhani is tenuous at best.
But the OL is in shambles. Levi's hurt all the time, and plays like he's hurt even when he's not, Whitworth's solid but Williams is getting older(though admittedly I haven't seen a drop off in his play, and Stacy Andrews wishes he could play as well as Levi does when Levi's hurt. Ghiaciuc wishes he could play as well as Andrews.
