I think your only choices are Torrey or Blackmon. The one thing you have to think about is Blackmon. He obviously won't be the better play in the beginning of the game, bc Torrey Smith has Joe Flacco, but you have to wonder, will Houston run the score up on Jacksonville where Blackmon will have more receptions and yards.
With Torrey I feel he is more like a 4 catch 80 yard player where blackmon could get you more receptions and yards but less chance of a TD, it's up to you, I just think it will depend on what you feel the second half of each game will be like.
Torrey is the safer pick, but I think Blackmon could have more points at the end of the day.
