According to an Illinois St guy on AGS their starter Kolbe was injured but did dress against SDSU to play in an emergency situation. However, reading
this article makes it seems like this was just Spack trying to spark the offense with a new QB after their lackluster loss to WIU the weekend before last. The ISU guy on AGS seems to think they'll play both QBs this week against NDSU but I get the feeling that it'll be Broadnax again. Given NDSU's struggles to defend against mobile QBs I kinda hope they play Kolbe, he's more the traditional passer whereas Broadnax is kind of a poor man's Tre Roberson (though he's just a freshman now) as a dual threat from what I understand.
Given the wind forecast I think throwing is going to problematic for both teams so it'll boil down to which team can run the ball and/or defend against the run better.
