When Brooks was drafted, Hubbard’s contract was ending and the only guy we had locked up was Miles Sanders. That’s a need. Positional value can be argued for first round RBs, but taking who many thought was RB1 in the 2nd round is a smart move.
From my perspective, you’re taking the bad angle as well as being negative. Sometimes the cookie crumbles with bad injury luck. Unfortunately, that’s difficult to predict. If we didn’t roster anyone who’s tore an ACL, we’d miss out on a lot of quality players.
