WR3 in Half Point PPR

I am a little thin at WR and need an upside type of play out of either Preston Williams or Paul Richardson. Who would you roll out?

Oh lord, there really isn’t anyone better on the waiver wire? If I had to choose I would go Richardson just because they are playing the Giants, but I wouldn’t feel good about it.

12 team league - other options are Stills, Dionte Johnson, Willie Snead, Humpries, and James Washington
