It's nearly impossible to get called for a pick play...unless you put your arms out in an attempt to block the guy you are picking.
Then IUs QB makes a huge mistake. 3rd and goal at the 18, and he passes up a big running lane to throw an incomplete jump ball. You aren't reaching the end zone, but down 21 you need to give your team a convertible 4th down. Instead they have to pick the FG.
