I agree. You never know what the draft is going to bring you and you can't make draft for need.
If you look at Walter football mock draft, the have 3 OTs in the top 10. None are named Alt or Olu. Walter football is usually ahead of the concensus this time of year and more often than you would expect, the rest of the pundits will have their mocks looking similar in March.
That is to say, there are up to 10 OTs who may be thought of as first round
Grades before all is said and done. The likelihood of one representing great value and BPA is fairly high in the first 3 rounds.
I have zero objections on taking an LT with either of our seconds or trading back up into the 1st with both seconds, a second + a third, whatever. I also wouldn't mind spending our 1st on a LT if we're picking around 20.
