The foul call pertains to an attempted trap defense near the end line. The Boilermakers ballcarrier picks up his dribble and is defended before appearing to either travel or step out of bounds, only for the center official to signal a foul.
What the referee saw was the defensive player move forward and into the offensive player, displacing the ballcarrier with a knee and causing the potential violation. Ergo, foul call.
But the focus of today's lines lesson pertains to a complaint about referees no-calling an inbounder who stepped on the line before inbounding the basketball. The purpose of this video and article is to reiterate that the end- and side lines are always out of bounds such that when an inbounder, standing out of bounds, steps on (but not across) one of these lines, that player is still considered out of bounds.
