I watch them play every week, so I know of what I speak. You've been reading the wrong paper, if you think their O-line is one of the best. They lost Joel Bitonio early in the season, John Greco two weeks ago & he and Joe Thomas are both in their thirties. The rest is a train wreck. Their LOS moves the wrong way more often than not, due mostly to OC Cam Erving, who doesn't have the grit it takes to play against grown men, & Spencer Drango, a rookie who still needs a year or two in an NFL weight room before he can hold his ground. The other players aren't worth mentioning. They don't need a top RB-they have two. Those guys just need more lanes to run through. They do need a TE, who they should get in the second-third round area. I would focus on OC/OG Pat Elflein with either their 2nd 1st round pick, or at #33. He's big, quick, & has a mean streak. Offensive tackles can be had after the first round without much drop as I said, & in free agency, which I hope they use extensively. They have a fine coach in Hue Jackson, & quality people above him. Those folks just need time to make their plan a reality.
