Question is, how much reshaping will there actually be? Barring transfers, almost the entire offense will be back for 2020. The only senior starters on offense are Noa and Williams, who are 'ORs' for the same WR position, neither of whom have made much noise this year. Those two plus Wyatt Mazour and Jaron Woodyard are the only seniors on the entire offensive depth chart.
So the question on that side of the ball is how much the existing players can develop in the next year, and how much impact can next year's crop of (redshirt) freshmen make? I've mentioned several times now that O-lines take the longest to develop, so in the long-term there's still at least some hope for those players, but I don't know if that will be enough...
