If Bell were there at 4 I think I would have to take him, but after that I'm not sure. If Bell were gone I feel like I would want to be taking Antonio Brown at that spot, but I am probably influenced by the scoring I am used to in my leagues and all of them are 6pts for a td. 2pts may not sound like much, but it's enough to have me go Brown no doubt if td's were worth 6, being worth 4 I feel brings Lacey into the mix. I can't trust a Chef, so Charles is out for me.
Also, 10 or 12 person league? I think this year at the 4th spot in a 10 team league I would go WR/RB/WR, but if it's 12 I think I would want to go with RB/WR/WR as my first three pics. (assuming snake format)
I think in a 10 team league you could get a stud WR at #4, then hopefully Jeremy Hill is there on the way back down, then another stud WR like BRandin Cooks. Some people are going to be wasting picks on the top two (or three if youre lucky) qb's and a TE (or two if Jimmy Graham goes) so you should have three solid picks at #4.
