In this week's RSP Cast, Matt Waldman explains why people can be too impatient with original evaluations, why people misuse workout data with running back evaluations, and provides quick takes on a pair of quarterbacks, running backs, and five tight ends in 2019's class.  

This week, I went solo to share some thoughts on scouting:

* RSP writer Dwain McFarland's new Film And Data analysis of Dak Prescott is a good starting point for thoughts on why we can be too impatient with player evaluations.

* Running back metrics: thoughts on speed and explosion, why they don't deliver the context of skill in a clean manner, and what else is needed to complete the analysis.

* Quick thoughts on running backs Nico Evans and Zack Moss, quarterbacks Riley Neal and Will Grier, and tight ends Albert Okwuegbunam, Tommy Sweeney, Noah Fant, Caleb Wilson, and Alize Mack.
