VIDEO: Doug Collins was crazy stressed watching his son coach Northwestern vs. Iowa

If you think it's stressful watching a child play a game, imagine watching your son coach.

Doug Collins, retired NBA All-Star, was the epitome of stress while watching his son Chris, head coach at Northwestern, lead the Wildcats to a 66-61 overtime victory over the Iowa Hawkeyes on Sunday.

With a few seconds left in the second half, Collins could barely look. 

The pressure ultimately forced him out of his seat.
