Horrible officiating at end of Pelicans game versus Mem

That's 2 games in a row where the officiating was horrible at the end of Pelicans game. Instead of a foul being called they called a walk on Walker. There's no way they were not fouling him. And that's 2 games in a row where a player was trapped and no foul was called. Professional sports officiating is getting worse and worse. Obvious somebody didn't want the Pels advancing. Pathetic that a multi-billion dollar organization has bush league officiating. I realize these games really mean nothing, but at least get the calls right and let the players decide who the better team is. And fouls should be called when a player is getting fouled!
