"Bradshaw is a talented runner who can run on the front-side and back-side of plays, has the vision to bounce out into the open field, and he possesses an underrated game overall. It’s unlikely that Bradshaw’s running style appealed to Grigson the most, however. Instead it was his pass protection skills, a very important skillset that Bradshaw excels at and last year’s Colts running backs did not.
Of the four running backs on the roster last season, only one — Mewelde Moore, a well-known pass blocker — graded positively (0.6) last year for his pass blocking, which he did on only 79 snaps according to Pro Football Focus. In comparison, Bradshaw registered a league-best 3.7 grade on a far greater 199 snaps for the New York Giants."
