Yeah I'd go with Gates this week because Floyd is out, and Alexander will be covered by Cromartie... Gates should thus be heavily targeted.
As for your other spots...... It's tough to bench Alfred Morris right now, he's been so good of late. I don't think you can bench Murray against NO, he's almost guaranteed to score at least once and surpass 100 total yards, and Knowshon has been getting a TON of touches. Problem is the Cleveland D is solid. I'd honestly flip a coin between Knowshon and Morris, but I personally would lean towards Morris (and this comes from a UGA fan who loves Moreno).
