You are obviously making something up because on the replay it only shows the PI. If you go back on your DVR and watch the play in real time you get a clear picture of Meeker blocking Jones. Someone chips Jones to start and then Meeker has him in front of him his hands are inside his frame the whole time and there is no grabbing of the jersey or anything. Meeker simply dominates him, there is no hold there. Maybe the ref thinks he sees something because Jones goes to the turf, its wet and Meeker outweighs him by at least 60 lbs but its a horrible call. If thats wrong someone put a video up that shows something different. If that play is called correctly ISU has the ball on the 20 with a little over 2 minutes left.
Iowa also gets the break on the run by Goodson setting up their last field goal where they completely ignore the block in the back in the backfield. If the penalty is called Iowa is backed up out of field goal range and who knows if they get close enough to try the field goal.
