The 2006 RB group might have looked better on paper (although, heading into the season, I don't think anyone should say that as certainly as you are, since Fui and Manase really were question marks at that point), but that doesn't mean that this year's group is going to be ineffective. The 2006 OL looked better heading into the season and almost certainly will still look better after the season, but this year's OL can still be effective enough for us to win 10 games.

BTW, Preator + Hannemann + Davis + Nacua looks way better on paper than J-Rob + Criddle + Gooch + Gabriel. Also, Juergens is better than Meikle. No one really went there on Twitter, though.
