As you know, I think the biggest issue with our offense is the play calling, not the OL (not saying the OL doesn't need work, obviously).
It's true that the line would presumably be in good shape. But you could say the same thing at other positions. If we used three or four first rounders on receivers, we'd have a great receiving corps, right? (Grigson drafted ONE first round receiver, and people act like he drafted a first round receiver every year.)
I'm talking about maximizing value. Use your resources as best you can. I don't want a budget OL, I have no problem with making significant commitments to it, but I really think we could protect well if we just stressed efficiency more. We ask more of our OL in protection than almost any other team. Even if you have five top 10 studs at OL, if we keep running this offense, Luck is going to face more pressure than he should. And if you really want to snap your fingers and fix the OL, you're better off doing it in FA, because good OL hit free agency. Good pass rushers don't, disruptive interior DL don't.
