People always say, You can never have enough Pass Rushers and CB's but for some reason fail to carry that thinking over to WR. You're not going to get All Pro WR's 1-3, let alone 1-6, but WR's 4-6 can be WR's who have certain high-end traits (they would obv be lacking in others), and for the new offense, you'd want those to be: YAC ability, toughness, and catching ability.
If Sanders sticks, he could be a guy you run on deep routes (stacks CB's consistently) when you want Hill and Waddle running short and intermediate routes.
But, Erik Ezukanma fits cleanly as a WR who should be efficient with his opportunities in this offense. He gives you YAC ability, toughness, and catching ability.
Curious to see what Bowden looks like, and Wilson has many of the traits that Ezukanma has, but Williams would have to show more than he has for me to think he's a good fit in the offense. YAC ability and toughness haven't been his calling cards to date.
