Where are all these ProBowl o-line going to come from? How are they going to pay them if they are that good. I doubt there is anyone out there that isn't significantly better than who they already have on the roster and PS.
We live in a world of instant gratification. One loss and fans are panic stricken. Believe me, bringing in someone from the outside is going to set things back not help. O-line is different than the other units. They need to play as one, and that kind of play only comes with time. After 4 games people are willing to throw in the towel? You would think they are 1-3 not 3-1.
Noteboom has never played OG and McVay didn't play the first unit during preseason. This is their pre-season. Demby was a disaster in pre-season but as I pointed out he was moved all over the place on each possession. Once he got to settle in at RG he started to play better. Did he make mistakes, yeah but he played better in his two starts than the veteran Blythe did in his one start.
My point is this. It takes time for o-line to gel...i.e. to understand what the guy next to him is going to do without it being spoken. This o-line is no where near that right now. Coupled with a center who is new to the NFL in terms of starts so his calls might not be what they will be next year. I think he's making some mistakes in his protection calls. Goff isn't at that point in his career where he can correct them.
They just need to play good enough, untll that unspoken communication begins to develop. So far they have. That is as much as can be expected. The one part that is a concern is that it's two veterans that are the weak links. But bringing in someone else's castoff isn't the answer. The answer is finding the solution with the guys they have, be it shifting or replacing or simply giving them help by playing two TE's. IMO the solution is on the team, they simply need to work it out. I think they will.
People need to chill and see what fixes McVay and Kromer come up with. Running better would be a huge help and IMO that means a change in blocking scheme.
