Trapper basically scored more than Lucas? He is a slow RB and he rarely retrieves the ball after losing it. I played him for 100 games to save money, I did save money, but it was not worth it at all, most LW's are lightning fast, but Trippier is lightning SLOW. He's not horrible, but someone like Bellerín is 1 000 000 bester.
Maybe defending, but he's probably better as a CB than as a RB
Not horrible if you use stay back while attacking
