The Bills need two of the three (Groot, Basham and Espinosa) to play solidly given the heavy emphasis on line rotation and the draft capital devoted to them. Yes, in a perfect world it will be three for three but draft probabilities would suggest this is highly unlikely. A better, more realistic scenario, is that two of the three play well an alone of those two is a “stud” player.
Time will tell but the Bills will have paid very dearly through draft capital if they do not get better production out of the group.
