I dumped him in a deep benched competitive 12 team league in Week 5. He is averaging about 25 yards a game since Rattay went down. The SF offense is terrible, so I would not expect him to all of a sudden turn it up with Dorsey or any other QB from here out.
There may be a game here or there where he gets a ton or garbage yards or a red zone TD, but unless you're in a really big league (16 teams or more) or in one that uses 4 WR's to start, I would leave him to the WW. Even a #3 WR on a team with an easy passing matchup is a better start than Lloyd right now.
