I get it, but I honestly do not believe that the coaches anticipated that the returning players would struggle this much. Let's not forget that we unexpectedly lost a pretty good starter in Britt over the Summer. Having him at RG would be a huge improvement on the right.
And, even if the coaches knew there was a problem over the Winter and Spring such there was time to comb through the portal, the portal is a tough place to find OL that can come in over the Summer, learn the system, and be ready to contribute as a starter after being on campus for a few months. Its an unlikely scenario to say the least. Do I wish they would have tried? Sure. Do I know that they did try and could not find anybody? I don't.
The reality is that we (and Petras) are just going to have to live through some growing pains.
