Im not saying thats a good reason to take OL. I don't think Ramczyk or Robinson is great value at 16- maybe Bolles but even he has issues since he's 25 and has limited tape out there.
But the Broncos being OT-less playing against Mack/Irvin, Houston/Hali, and Ingram/Bosa each twice a year would be sad/funny.
On a serious note though, the value of non-LT OL in the draft should be higher (not QB high, but still high). Its not really possible anymore to get even decent OL- guards, RTs, centers- in free agency without dropping over 8 mil/year and especially with this draft I think if the team wants to get difference-making OL this year, they'll need to reach.
