I agree with your take on how the BPA approach to the Draft is intended to work. Obviously, it would not make sense to use it as a strategy by itself without first establishing a hierarchy of needs for the team. Overall, the Ravens track record in the draft has been moderately successful over the long haul. However, the reality is that our most recent drafts have been less successful than they have been in the past. It doesn't take a rocket scientist to figure that out. My problem with our draft strategy is that it seems that we are bypassing a lot of BPA players b/c the FO and the coaching staff apparently cannot agree on the hierarchy of needs. For instance, we are now four years removed from the Super Bowl and we have not drafted a top-notch CB to complement Jimmy Smith. Will it be Tavon Young? I doubt it. We haven't drafted a suitable replacement for Ed Reed either. Is it Matt Elam? Nope! Some of the O-linemen we have drafted are absolutely terrible. James Hurst was recently rated as the worst O-lineman in the NFL. No matter how it is intended to work, there is further evidence that our BPA strategy is not working as intended. Many of our draft picks who have become free agents have not panned out for their new teams. I hear many Ravens fans comment on that repeatedly on this blog. So, were they successful draft picks for the Ravens? Also, if one takes an objective look at our roster lately, one must conclude that several of our better players have come to us by way of FA. In summary, one could also conclude that the track record of "The Great and Powerful Wizard of Oz" is not as stellar as it should be, given his awesome reputation in the draft.
However, I do take exception to your last sentence and here's why. The reality is that if the BPA pick doesn't pan out, he may not really be the BPA, assuming he's not injured like BP was. In other words, we cannot afford to miss on draft picks that are so important to the lifeblood of the team. Hindsight is always 20-20. I get it, but I think the real problem lies in the effectiveness of our college scouting, including the combine, and the organization's apparent inability to reach a consensus on the hierarchy of needs. Is Harbaugh on the hot seat yet? IDK but if he's not a part of the solution then he's part of the problem.
