Ya, Glow is the weak link of the OL right now... but is still an improvement to what we had when Ballard/Reich took over this team. He didn't have a good game against HOU but they also have one of the best defensive fronts in the NFL.
Nelson is a once in a generation talent, I don't see any guards coming out this year close to him. While I trust Ballard, I highly doubt we'll take a G with our first rounder given the fact that we can use help at several other positions and there will probably be better positional value there for us in the first at other positions.
....Any Given Sunday...
I think the point of the Salary Cap in the NFL was to make this a league of parity. For the most part, that's what it is (we have a few teams which seem far and away better than others -- the Patriots, e.g., ... and then a couple really bad teams -- the Dolphins this year, e.g.).
For the most part, teams are just a couple injuries/suspensions/ejections shy of losing very good players who change the entire dynamic of their team and if any team comes out with their best effort vs. a team w/ a lackluster effort, there are a lot of things that can happen on Sunday.
I don't disagree with you that we can still lose to the Broncos. I also don't disagree that the Colts didn't show up to play their best brand of football vs. Oakland. That said, OAK is a better team than most people think and my original post was in response to you suggesting after the loss to the Raiders, the only way you'd look by a team is if they have 0 wins (IMO, you were suggesting OAK was a very bad team).
Regardless, I don't think it's smart to look past a 0 win team, either. It happens very rarely, and almost every team that has 0 wins has players on them playing for their personal pride (not just this year, but every year). Heck, in 1997 we were 0-10 and played the Green Bay Packers who were 8-2 and beat them. The Packers wound up 13-3 and lost in the SB to Elway's Broncos... we were 3-13, there wasn't an honest 'expert' anywhere who would've thought the 0-10 Colts would beat GB like that, but they did it.
So yea, I agree w/ you about starting to buy into Reich's motto of '1-0' -- that's what it takes to win consistently in this league and not let up against lesser opponents.
