Personally, at a certain point, college production becomes irrelevant to me since there is an NFL body of work to judge. In college, they played under different circumstances - I.e. different coaches, schemes, OL, QBs, WRs, opponents played, etc.
When on the same team in the NFL, their circumstances are similar. From what I can tell now, Corum is similar but KW has superior vision and patience. My hope is that Corum can grow into what KW is.
Edit: As for how their rookie seasons looked, I saw Kyren's elite vision immediately.
