'You don't put rims on a Hoopty'
No, we shouldn't be more open to Drafting an RB in the 1st (to improve upon last season's porous Defense) as the roster does not, currently, call for or support that notion. We do not possess the leverage to draft a luxury, when our D could not generate pressure & Luck could not stay healthy (due to an under-performing OLine).
In his inaugural offseason as Our GM, Ballard addressed questions about FA with a "build within" answer, THEN in response to last year's lackluster roster, he signed a *Record number of FAs to Indy, with only 1 being an OLinemen. Heck he brought in two TEs and one of them is known for playing College Basketball.
Ballard greatly values the trenches, as was seen in his Free Agent interests & the Hankins signing $$$, so if he brings in a whole bunch of players and JUST 1 is an OLineman... then expect a Lineman to be drafted this year. Furthermore, if he wanted to bolster the OLine he had the $$$ and opportunity to do so, yet didn't go after a Day 1 plug & play starter on a Pro Bowl level; he brought in a veteran to supply competition & depth. Clearly, he's not seeing our line on par with "the boys", so he knows better than to put nice rims on a hoopty.
By addressing this question, we have been open enough, but should not be any more than that unless: that 1st round RB can take angles like Ray Lewis, hit like Bob, and cover like Deion then its best that the FO address RB later in the Draft or sometime in next years. - As much as I like some of the RBs in this class, I prefer to start Gore this season, as he can rush for one more 1,000 yard stint & then draft a rookie from next year's class after this young, competition OLine gets more experience playing together. That's how Atlanta got to the SB w/ a prolific Offense, they're boys were the same starting 5. And We don't know exactly who or WHAT we have yet.
