After two years of subpar WR play, I am one who suspects that there is a problem with development at this position. I hope 2021 is a lot better for this group and I think it can be, but one more year that looks like the last two will turn my suspicion into a firm conclusion.
It's hard to understand how we have gotten so little out of every receiver that Frost has recruited other than Robinson, who promptly left the team after two years. Houston, Nance, and Chase (no longer with the team) from the 2019 class have barely seen the field in two years. From the 2020 class, Fleming left after a few games, Brown caught a few garbage-time passes, Betts caught something like 12 passes, and Nixon was injured. The seven players I listed have combined for one touchdown catch in their careers so far, and these were all 4* or high 3* recruits coming out of high school / prep school.
