I think the less we hear about the OL in the preseason, the better they are probably doing. You only hear about the OL when they screw up.
WRT Robinson, he is under such a microscope that every mistake he makes will be magnified and it will seem like he is failing again to be the LT we were promised. But his mistakes need to be considered in perspective of his overall play. All LTs make mistakes, especially early in preseason. Are Robinson's mistakes that we might be seeing now truly cause for concern? Or has his overall play improved enough that we should take hope? Again, we always hear about the mistakes for these guys, and the good stuff gets glossed over. I am hopeful because the reports of Robinson's mistakes seems to be at a fairly low level.
And, overall I am very bullish on the OL. This might be the first year that Bodreau has a unit that is young and relatively healthy and somewhat experienced and deep that he can mold.
