To my way of thinking , the biggest hole in the roster is OC. Do the Rams need an edge? Sure, but they had the #1 defense last year and even if not as good in 2021, it will likely be good enough to win with a dropoff in edge play.
If Meinerz is there for the Rams in the 2nd, don't dick around and trade down a few spots and hope he is still there. Just pick him. They obviously like him and it would seem he has a high floor and a really high ceiling.
I dunno about LT. I though Boom looked serviceable when he filled in last year. I'd like to know what FA LTs will be available next year. If there are few that will hit FA, it makes it easier to pass on using a high pick on one this year.
