This, this, this. I think Brillant would make our ability on set pieces 3x better due to a better knowledge of getting a head on the ball from a cross. Without him, I don't think we've had a CB (or any starter) that could threaten to do so from a corner or set piece. One of our only goals from a CB that I can think of, since the start of the club in MLS, was KWS with his laser shot last year (Still don't know how that happened).
Defensively, I also feel like Brillant would've been in a better position seeing that Saunders clearly wasn't on the Orlando goal, but that could just be bias in me really wanting Brillant to start over Hernandez.
