At some point you have to stop with the "idiots" comments and all of that. Just make your argument on substance.
The offensive line does take time to come together. However with all the player and coach movement - teams, coaches and players have gotten better at tightening things up in less time. Offensive lines staying together and gelling in time is a thing of the past. The same goes for the defenses - so it does even itself out.
There will be some communication penalties and missed assignments - it's naive to think that won't happen.
I hate the excuses argument. Allen is heading into his second year with likely 4 new lineman. It won't be an excuse if that all doesn't come together - it's expected. It won't come all together. Allen is building a career and most believe he'll take another leap this year. To say he and the offensive line are without excuse is just following the same vein of what you detest.
