Respectfully disagree. I think Pancake and Maiu can be AAs under Mario and Mirabal. But I don't care how physically ready you are as a first year college student, the probability of you replacing two experienced and talented players like Rivers and Nelson as a starter is a huge stretch. Those older guys may not be Day 1 or Day 2 picks. But both will get drafted and play in the NFL. They're not scrubs.
Personally, I'd rather have Rivers starting inside opposite Lee, with Cooper rotating in, and going for a GT at the other OT spot opposite Nelson, with Samson, Mauigoa and McCoy rotating in.
