Daniel Jeremiah - “Everyone is moving up for an OT”

I've read/watched reports this off-season about how the tackle position is weak for many NFL teams.
If true, teams scrambling to get a tackle makes a lot of sense.

I don't have any articles to back this up.
I watch and read so much about the NFL, I wouldn't even know where to begin looking for that info.
I think it's reasonably evident, based on how infrequently good quality starters at OT become available as free agents or via trade, how highly and quickly they are then signed on those rare occasions, and how highly teams tend to draft the big guys every April.

Look at the price (trade and contract) the Niners gave up to acquire Trent Williams. And only after a prolonged period of Williams refusing to stay in Washington forced the Commanders into considering trading him. And yet, the Niners would tell you he was worth every penny and draft pick they gave up.
