Since it doesn't look like Dez will be playing against the 49ers on Sunday, would WR Cole Beasley be a good fantasy option? He leads the Cowboys in receptions and yards. He won't get any TDs, but he always seems to be open for Dak. Dak and Beasley seem to have a kind of rapport going.
I have him at 8 points in a .5 point per reception league. He'll get extra attention with Dez out and I assume the Cowboys will continue to protect Dak with a run heavy game plan. Also, the 49ers seem to struggle against big and tall WR - http://www.fftoday.com/stats/fantas...&Season=2016&PosID=30&Side=Allowed&LeagueID=1
