I think it's too early for Wilcox at this point. He's played Safety just one year, and that was at a Division II school. He was a slot WR/RB hybrid before that.
He's an interesting guy, but he's a pure athlete that is a massive project at Safety. Long term, could be a solid selection. For the next three years, he's a special teams guy only in all likelihood.
I had him in the 6th Round, but I'm risk averse. Small school, only one year at the position. Too risky for me.
