I don't agree. We've had decent lines. Most notably in 2010, and 2012-2013.
Our 2010 OL was not decent. They were arguably the worst run blocking unit in the NFL and were mediocre at best in pass protection...but Shurmur's offense got the ball out of Sam's hand so quickly that sacks were kept down.
That year, Steven Jackson averaged 1.2 yards before contact behind that OL...worst among the top 20 HBs in rushing yards that year.
The OL was comprised of:
LT: Rodger Saffold
LG: Jacob Bell
C: Jason Brown
RG: Adam Goldberg
RT: Jason Smith
Bell, Brown, and Goldberg were all out of the NFL after the 2011 season. I don't even need to rehash the Jason Smith story.
2012 and 2013 weren't decent OLs either. Just look at the guys on those OLs. The 2013 OL had a good stretch when Saffold was inserted at RG...but one good 6 game stretch in the past however many years doesn't do much for us. The OL needs to be fixed. Much moreso than the WR corp.
We've had some injuries and one or two bad players, but no NFL team has a perfect O-line from start to finish. If that's what it's going to take for this team to have some offensive success, then we're simply waiting for the odds to be in our favor.
There are NFL teams out there that have solid or better starters at every position on the OL.
And we can very easily plan for injuries by having depth. Which is also quite important on the OL because you know at least one or two of your OLs are going to get hurt...even if they don't miss extended time, they'll miss parts of games with bumps and bruises.
What's it going to take for this team to have offensive "success"? A QB.
What's it going to take for this team to be one of the best offensive units in football? A QB and an OL.
I think our resources are best spent making our OL great. The games are won and lost in the trenches.
When you don't have good receivers, defenses can crowd the box. When you have a stable of good receivers, defenses have to respect the threat.
That's not really true. It's not receivers that kept the defense out of the box, it's the passing game as a whole. Which means the QB and the OL.
Frankly, I say let them crowd the box. Because our WRs are good enough to make them pay if they do if we have a QB that can get the ball to them. And if we have a top tier OL, they'll immediately regret crowding the box.
Defenses may respect a great WR but they're not going to respect your passing game if you don't have a guy that can get the ball to him. And you're not going to beat teams through the air if you can't stop a four man pass rush.
When you can consistently stop four man pass rushes with your OL, you can have your way with a defense if you have a capable QB. Because you force them to blitz and leave your WRs in more advantageous match-ups.
Our WR corp currently is:
Britt(assuming he's re-signed)
Quick
Austin
Bailey
Givens
Givens is replaceable...but I don't see a need for Cobb. And if you do see a need for a top shelf WR...a guy that defenses will have to respect. Go draft DeVante Parker, Kevin White, or Amari Cooper. Those guys have the ability to be #1 WRs in this league. I don't see that in Cobb.
I don't see a guy that will push defenses out of the box if that's your goal. I don't disagree with you that the right WR can force defenses to back off...but I do disagree that Cobb is that guy.
