I'd Drop DMac. He's injured for several more weeks before coming back to play in a three-way carry share for the Raiders. Not an ideal situation fantasy-wise. However, I wouldnt use that #1 waiver priority to get any of those guys unless youre looking pretty bad at WR and really need to get someone. If this is the case, I'd go with Moore. Collie and Austin got so many targets this week due to receivers ahead of them on the depth chart being temporarily out. Eventually Gonzalez and Williams will return and these two will be relegated back down to WR3 (in Austins case) or WR4 (in Collies case) in all likelihood. Nicks and Maclin are rookie WRs, who are always notoriously inconsistent. They are also currently third of their depth charts. Moore is on the Saints pass-heavy offense. His potential is just greater than that of the others.
I have VJax and Megatron. I also have Breaston. Not sure if I need help that much but with Mega's injury just wanted to see if I should shore up at receiver.
