No. There are only two guaranteed misses in this draft, not securing an edge rusher, and not getting talent to build around Tua. I'm confident we'll get those two things. RB's aren't make or break for many teams, and we have some talent in case we don't draft a RB. I suspect we'll draft a RB somewhere, but if we don't, there's always FA ... if we make better decisions than Jordan Howard and Matt Breida. While Etienne, Harris or Williams would be ideal ... the entire concept of Best Player Available (BPA) means you cannot hone in on a specific position. And as far as cornerstone players, RB's are not it at this point of time in the NFL.
We have enough resources to get BPA at important positions like Edge, WR, OL. With the WR and CB class being deep, I'm confident we'll get one of each somewhere. RB's can be found everywhere in the draft these days, so if we need a stop-gap guy, I think we can find one. If we add one of those top 3 RB's, that helps out our offense for 4 years. Either way, I'm more interested in improving the talent level of our roster, so taking BPA is my preferred strategy as long as we secure an Edge, Weapon and Protection for Tua. Our needs align pretty well at #6 and #18 to get a WR and Edge. If we add an OL at #36 or 50, we should have it covered.
