Obviously, the better OL we have, the easier success will come. That's not exactly a bold statement. We all believe that. I think attributing our 2012 NFC East Championship to a 'gimmick' is sort of outrageous. That 2012 team, lead by a rookie QB no less, reeled off 7 straight wins, including sweeping both Dallas and Philadephia and beating the eventual Super Bowl champion Ravens in OT. We had the 4th ranked offense in the league and the #1 ranked rushing offense (averaging 170 yards per game). Did we overuse the read option? Probably. Did we have poor pass protection? Mostly. But writing it all off as a 'gimmick' - I think that's an epic overstatement. And all that success was just 2 seasons ago. The point of my blog is that we have added significant offensive talent. We have also arguably improved the OL - although they will run different schemes and it will take another season or two to add the additional pieces we need there to be dominant. But I think we will score a huge number of points this year. And it will be the Redskins offense, and how anyone is going to stop it, that sports talking heads will be discussing, not the Eagles offense this year.
I do agree with your overall point, that we need big uglies, and some Pro Bowl big uglies in addition to TW to be the kind of super-solid team that wins 9-10 games consistently and to be perennial Playoff contenders.
