I dunno about Daniels with your other HOU players, however, if he is going to score points - it shouldn't matter. I normally do not like starting multiple players from one team. As for Watson, I have the same issue with Watson and am going with Winslow instead.
I really think I'd go with Pettigrew if you have him anyway. He gets plenty of targets and may have a big day.
