This is a question i've had for a long time. I looked at the san Fran o-line and those guy's were huge across the board. I think 3 or 4 of them were 1st round picks if i'm not mistaking. The interesting thing i noticed was how athletic they were as well, Altho Matthews got the best of staley at times he did hold his own against Matthews who's fast and strong. That is a line built to be able to run block when it's time to grind a game out and pass block when needed. Then theres our o-line. Little and slow imo. They are small compared to most nfl lines and you can even tell when you see them on tv which should make them look bigger. I think that's one of the reasons they can't pass or run block right now. To darn small and slow...how many plays did you see where the guard pulled to lead the way for a rb? I saw San Fran do this 4 or 5 times in the course of the game and it worked. Some GM's draft to build good pass blocking attacks and some draft to dominate on the ground but i can honestly look at our line and say wow, these guy's can't run block or pass block. Maybe we need some more brothas on the o-line haha. Jk our "brotha's" can't block either.
