Yeah, I think OL is important as well, but can be masked by the elite QBs of the world.
I don’t think you need an elite LT, just a good one. Same goes for center too. Give me Garrett, Bosa and Watt over Armstead and Tunsil every day of the week. A great DE can dominate a game and is very hard to come by unless you’re picking top 2-3. I think you can find reasonably good LTs RDs 1-2.
A true shutdown corner is also very hard to come by. The Revis Island, Sherman or Deion in his prime type of players rarely come by, but if you get one, it can open up things for your defense in a mega way.
