Beware the 'late riser' prospect. Teams can kid themselves based on need and recency bias.
Remember when Zach Wilson made a couple of combine throws that suddenly 'elevated' his stock?
The scouts of each NFL team build up their files on these prospects over a few years, refining their grades as they get closer to graduation/declaring for the draft. The concept of late risers and fallers has always felt to me to be mostly the domain of draft media creating frama* and foolish teams that don't trust their own scouting.
* Fake Drama = the draft media needs fresh stories for clicks. If they reported that most teams had pretty much finalised who they wanted and where, weeks or indeed months before draft day, where would they get their breathless updates about player X from?
