Well, 20 years ago you couldn't get through a draft without a Top 10 RB pick. Less than 10 years ago I remember people on this board saying pick #16 was too high for an OG. Tell any team in the league today that they can get Zach Martin with a Top 10 pick and he wouldn't last until #16.
The game is evolving. The TE is no longer viewed as a guy who has to be good at both blocking and receiving and will be doing equal parts of both. Teams are willing to sacrifice both skill and utilization at blocking if they can put their TE out there and the defense has nobody to line up against them. They're just monster WRs at this point.
I don't think the good teams look to what has historically been true to make organizational decisions. They anticipate what is next and try to get ahead of the curve. Of course, now we're probably at a point where you can't get ahead of the curve regarding the TE position because there are too many players that are outproducing 1st round WRs. Kelce, Kittle, Mark Andrews, Darren Waller (even limited by health), etc are all certainly worth 1st round picks based on productivity.
I know nothing about this proposed TE, but if Dallas is going to go TE my first thought would be to see if you can trade for Pitts. Atlanta says they aren't going to trade him, but they aren't going anywhere with him and if there's someone on the clock they highly covet, they might start getting wild. That would be my preference for a 1st round pick used on TE, but like I said, I don't anything about the current TE class.
