The main problem is that we underperform at too many positions on the line, but we can't realistically replace every lousy lineman with somebody else who is immediately better.
I actually think we will probably go into next year with the same tackles, Gandy and Peters. Not great tackles, but they are at least average. I guess I'm willing to overlook Gandy's big whiff on Saturday that allowed Holcomb to get splattered.
The interior is where we really need change. I think the jury is still out on what will happen to Teague and Villarial, if only because we may need bodies. I think Preston is given the chance to take over the center spot, but the question is, is Teague too expensive to keep around anyway?
Villarial, IMO, will probably be given the opportunity to keep the RG spot, but I don't know if he's more expensive than his worth.
Then there's LG. If there was ever a position I would like to see a name free agent come in to patch a spot, that would be it. The salary saved by slicing Williams and Anderson should cover that.
A high draft pick (or two) at tackle or guard should provide adequate depth and preparation for beyond that.
