The o-line was a point of strength because it returned 4 starters with 3 of them having at least two years of experience. The center was a 4 year starter but he is being replaced by freshman Mike Matthews, brother of Jake Matthews. The two guards are sophomores and will likely stay for two more years. I think the inside of the Aggies line will be fine over the next two seasons, but I have no idea what is going to happen with the tackles.
Matthews and Joeckel are headed to the NFL and Joeckel could be a No.1 overall pick so I see no reason for him to stay. I've heard they are making their decision together so if Joeckel goes so will Matthews. If Matthews would stay and slide over to LT we have a RS-Freshman and a true freshman sitting behind him on the two-deep that could play on the right. Matthews could also increase his draft stock and go higher in the first if he sticks around. The good news is all of these guys were recruited by Sherman and the one thing he did well was build an offensive line.
