We've got arguably the single best one-two punch at RB in the league, and a very effective weapon in that. And yet a significant portion of the fanbase (if you consider this board representative) really seems to want to cut the power of that weapon in half.
And please don't give me that we have enough depth to keep it going even with the loss of one of the top guys. There is no way anyone can reasonably suggest that any of the other combos (Williams-Goodson, Williams-Sutton, Stewart-Goodson, Stewart-Sutton) is anywhere even close to the quality of Williams-Stewart as a rushing tandem.
There are other teams that have put all their eggs in a single basket with "workhorse" backs, and it's been rough. These days, even when healthy, neither Adrian Peterson nor LaDainian Tomlinson is what they once were, and the decline has been quick (almost sudden). One of the prime reasons for that is their being used as the "workhorse" for their team rather than as part of a 'two-headed monster' like the Panthers and some other teams prefer.
Knowing that it tends to shorten the shelf-life of good runners, I can't understand why on earth people want us to switch to that model.
As far as using a high pick on a RB, no matter how high you go you're still trading a proven commodity for an unproven one.
its not even debatable.
