Not one of the options, but I would try and trade down in the first to get a 2nd rounder back. Draft some OL and role with Darnold. Also, if possible trade CMC for another 1st. I would draft OL with our first 3 picks, getting a LT, G, and C. Get them some experience their rookie years.
Then when we end up with the 1oa we can have our pick of the QBs in next years class and we should have a decent OL to put them behind.
I wouldn't go and spend money on any OL FA's until next offseason with this scenario.
