If the time of the trade talk was before last season (and maybe shortly after the 2017 draft), it makes sense.
Let's credit Higbeast for the work he's put in to his craft. He was a converted WR in college, that played in WKU's uber-pass happy offense that the Rams drafted to be an offensive weapon. Under Fisher, he fizzled - no surprise. I mean, it would have been pretty easy back after Fish was dusted to mentally lump Higs in with Kenny Britt and Brian Quick.
Then under McV, Hig's turned into an indispensable physical pass blocking TE. There was also a video this year showing his ability to, pick/screen down field, as an eligible receiver, without getting flagged. On top of everything, he is sort of useful as a pass catcher.
So yeah, looking at him today and looking at the proposed trade way back then doesn't look right. I give Higs credit for what he's become.
