Kickers are a funny breed. I like Hausch Money, he started slow last year but finished well.
But, the one thing I see is the McDermott does not seem to trust him for any long attempts. That may just be his conservatism showing, or does he just not think Hauschka can make them consistently enough?
More likely, its a combination of both. It always seems like a strain for Hauschka to get it to the end zone on kickoffs, and we know McD is not a big risk taker and will trust his defense over a long try when given the option.
But its also that conservatism that probably keeps Hauschka around. Stay with what you know, rather than risk an unpredictable younger option.
