#4 is an interesting formation.
Kiser is on the line playing outside the LT, looking to contain the edge. Young is the MLB, playing deep. Samson run blitzes between Kiser and Gaines, who's playing end.
Ebu misses the initial tackle, though the LT does a good job of keeping him out of the play. Kiser slides over and it looks like he's expecting Elliott to take him on, only for Elliott to dip his shoulder. Kiser tries to shoulder tackle him, and Elliott slides off. A last minute attempt at a grab by Kiser fails. Maybe If he'd tried to wrap up initially there might have been a different result.
