muff

Grimm muffed two punts against the 49ers, withering turnovers that could not have come at a worse time for him.

He muffed a punt that set up the Saints in scoring position and later bobbled another before recovering it, prompting rookie Luke Grimm to take over punt return duties in the second half.

An errant snap or muffed catch can delay placement by one- or two-tenths of a second.

He also has made a few costly mistakes in the process, such as muffing a punt against Wisconsin and dropping a key third-down pass against Minnesota.

It will come as little surprise that the goalies in the crease, drawing on years of experience and wearing the right gear for the task, easily turned aside nearly all of the muffed penalty shots.
