Marcus Wheaton or Terrance Williams?

This would be my 2nd wr and are my only options. 14 team league, .5 ppr, with very few bench spots, and I have Welker molly'ed out on the bench.

I started Williams last week and he had a decent game, but only because he caught a meaningless TD at the end of the game. Plus Romo was horrible.

Picked up Wheaton this week, who also had a decent game and was targeted much more on a team depleted at wr.

I'm leaning towards Wheaton because of targets and the matchup, but he has a much less proven track record.
