What Jalin Hyatt did here in 2022 was incredible, but that guy was not going to be a productive NFL receiver regardless of what system he played in in college.
As far as skills as a WR, he really only brings one big one to the table, which is straight-line speed (and he didn't run the 40 as fast as you'd think at the combine either). He isn't a great route runner and doesn't have great quickness/make guys miss ability. Doesn't have good size either.
I think the label of "system guy" is an unfair sometimes, but unfortunately I think it was right with Hyatt. His success was a function of Heupel's offense creating matchup issues on the outside between him and a safety. I think the NFL strongly suspected that too - it isn't often that a Biletnikoff winner goes in the 3rd round of a draft.
