I'd sit tight also, and I was one of those Welker guys who suffered in two leagues. Thankfully Matt Ryan made up for it and I got a W in one...
Anyway, Hillis should see goal line carries moving forward and more work. I like McCluster in Free agency, think he could end up being a mini percy harvin type player who could start at RB (awesome for PPR leagues). Still I would hold onto Hillis for another week.
