The Michigan quarterback gained almost 200 yards rushing last week as well as showing great accuracy throwing.
During a press conference he said "I don’t know that you ever can prepare for Denard Robinson at the same speed that he plays."
As they gear up for their game against Michigan this weekend Kelly said he realizes that there's a big difference between defending Purdue's Robert Marve and Robinson.
But Kelly apparently has a couple of ideas of who he can use in practice to emulate Robinson but refused to release names.
Chief among them may be back up quarterback Nate Montana who runs like his father Joe and also has a strong arm.
