Not so much evenly distributed, as determining the areas of needs that are imperative. In this case, I would say O-line, and edge defender are the primary concerns. Once those are addressed, concentrating on a single area is certainly a reasonable option.It's hard to argue with balance, but balance means different things to different people. Do you mean an even distribution of resources? That'd be like saying you have a balanced diet, because you eat as many candy bars as vegetables.
As to the candy bar analogy, I agree. That would be paramount to drafting WRs, or RBs with our top picks, as some have actually suggested. They want the exiting "sweets", but don't want to eat their asparagus, which is actually good for them in the long run.
