I think Beit was just being overly enthusiastic. He wanted to show what he could do to his former team and as a result overcommitted! He and Perquis had switched positions which is standard fare but when Beit dove in like that, something I don't think anybody expected, Perquis was in no position to recover particularly against a speedster like Manneh! The man is fast and there's no way that Perquis (or most of the CB's in MLS) are going to be able to keep up with him.
