Yeah, Moulds and Evans are going to be the goto WR's in Buffalo. I think Moulds is set for a nice comeback year. I wouldn't waste a pick on Shaw, but I'd keep an eye on him during the preseason to see if for some unforseen reason Evans can't lockdown the starting job.
If you're really liking Shaw, I think in most leagues you'll be able to grab him as a free agent.
Oh, and with all due respect Mookie, Wrong Forum.
