spanning the last couple of years with Verse and I saw that he was invisible for large portions of a game and would make a splash, big time play. I would watch #5 at the snap and he would get eaten up, or pushed out of the action. I have also watched Latu games and I saw him in almost every defensive snap, he may not have made the sack, but he would move the pocket or change the idea of the play.
IMO Latu has more impact play to play over Verse, at least in the games I saw.
