Quality > quantity. The quality is way more apt to be at the top of the draft vs. a mid/late 1st pick. Hopefully we're not going to be picking at the top no more than another year or two so while we're here we'd better be looking at the most quality/high value assets we can get.so the more bodies they get, the better.
I've tended to go against this type of deal on RGM trade boards because I've been less than impressed in the limited amount of looks I've had of Williams. I'd be willing to defer to others who know him better than I do tho.
