You apparently vastly overvalue RBs.
Sure.

* Also, the top two rushing teams had QB's lead the team in rushing.
Asking two rookies, one drafted 212th and one not drafted at all, to come in and be immediately effective is a huge ask. Throw in Pollard coming off a late-season ACL injury and it ranks right up there with the "anyone can run behind this line" and "You don't need a #1 WR" thinking that cost this team a wasted season.
Hoping that Pollard is healthy, and Ronald Jones can be effective, especially early in the year. Counting on two unheralded rookies is the same, no accountability leadership type errors that keeps holding this team back.
